Hello Mark and list, 
 
You asked:
 
What is the serial number of your home?  As always I enjoy feedback.
 
in 1889 Edison originally envisioned his phonograph as a business machine.  The 
standard speaker has both cutting and ball playing stylus, with the arm all the 
way up to the lug and the knurled screw extracted level to the lug the standard 
speaker is in play position, when you rotate the arm by turning the screw down 
it puts the speaker in the record position.  The weight of the standard speaker 
is light so it is suitable for voice recording and reproduction.  When you made 
a recording and then played back there was not a problem.  When you removed the 
record the standard speaker had tracking problems due to almost no lateral 
movement, the stylus bar being the only scource of lateral movement.  
 
During this period of time listening tubes were used, again business 
orientated, only the secretary need listen.  
 
The automatic reproducer with its .8 ounce weight tracked automatically and 
gave an increase to volume.  The speaker arm was blank as were the early 
automatic reproducers which got the Reproducer stamp in the 50,000 range.  With 
the automatic reproducer the arm adjusting screw was no longer necessary, but 
the lug was needed to keep the reproducer in proper orientation, but with the 
small amount of machines Edison made it was likely not worth retooling and the 
lug served to provide reproducer position.  All the recessed top devices, 
recorders and reproducers along with speakers share serial numbers.  Just over 
212,000 were made as opposed to 2.12 million of the B to K reproducers which 
also share serial numbers.  
 
Around 190,000 the automatic weight went to 1.2 ounces, around 202,000 the 
automatic got a limit loop and pin along with a hinge block.  In 1901 Edison 
took the bottom of the automatic and created a new dome top, an idea he could 
have gotten from Mobley who made a domed top for the automatic and hanging 
weight.  This new reproducer was called the B and it replaced the automatic on 
all machines.  Like the automatic it had no notch so the lug was still 
necessary.  Around 18,000 the automatic got the notch for the centering pin and 
was still used on all machines.  This remained the case until around 30,000 to 
40,000 when the B lost its arm.
 
The notch and the centering pin eliminated the need for the lug and I believe 
Edison updated existing carriages by removing the lug and adding the centering 
pin and set screw and elimination the sliding holders that held the reproducer 
in place as  owned a suitcase standard this was done to.  In 1901 Edison 
developed the C and around 25,000 the C joined the B, around 30,000 the D 
joined in as well, all three reproducers were not identified and had blank 
weights at first.  
 
When the B lost its arm around 40,000 and was stamped Model B the top does not 
say reproducer on it, there are three types of the early top without reproducer 
on it.  Until around 110,000 when Edison produced tops that say reproducer the 
arm was for ID purposes.  The arm remained on the C sporadically through 1906 
and the B is even less common with the arm after 40,000 as some were made to go 
on Concert and Edison Bell Duplex concert machines.  The D always had a ball 
stylus until they were updated later on.
 
The B did not sound very good with molded records so around 110,000 the B 
weight was made to have a lead weight held in place by two screws, this still 
did not prove satisfactory to Edison so the B got the lead alloy 2.2 ounce 
weight and the volume was then equal to or greater than the C with its 1.2 to 
1.3 ounce weight.  
 
When the automatic recorder joined in around 30,000 the automatic got lettering 
on the body as the new recorder had, prior to 30,000 the automatic reproducer 
body is blank like the recorder.  Because the automatic recorder was designed 
for voice production only the recorder is not efficient and without an 
extremely highly skilled individual with a tremendous amount of experience and 
skills the automatic recorder does not record very well and leaves a shallow 
groove.
 
In 1901 Edison redesigned his recorder to match the early B and a much deeper 
groove resulted.  The first dome top recorder has an aluminum cutter holder 
with a tube and tiny arms, this was easily damaged and the holder got wings.  
The wings gave way to the common holder, the next change was the holder was 
made of copper, then the holder was nickel plated.  The final version was a 
holder that looks like the 4 minute recorder that is rarely seen.  Edison made 
and sold the 2 and 4 minute recorder at the same time in 1912, and he made them 
both after the fire.  The 1915 ICS amberola 30 came with a 4 minute recorder.  
Edison also made the CHK into the 1920's.  Edison began to plate the copper 
diaphragms with nickel, I have CHK diaphragms that are nickel plated.  I have a 
model H that was rebuilt by Edison in the 1920's as the nickel plated diaphragm 
and corks gaskets testify to.  
 
The dome top recorders share serial numbers, just over 613,000 were made.
 
All Edison reproducers and recorders were meant to have a serial number, I have 
seen one recorder that was skipped.  Edison did make mistakes and was too 
parciminous to recall machines with visual defects only.  Like me Edison did 
not waste so you see earlier parts on later machines and reproducers.  The flat 
top O and N, the dome came out by 42,000 yet I just saw a flat top N with a 
serial number in the 54,000 range.  By 70,000 the C weights had the holes, in 
1910 Edison made C's with the early no hole weights, I have one and know of at 
least 2 others in the A830,000 range.  
 
Regarding the speaker on eBay with no serial number, it was skipped or has a 
reproduction top that could have been made in the 1890's.  Remember the 
reproducers sold at a price equivalent to a days wages or more so I have seen 
early home repairs including a skilled machinist that turned a speaker into an 
automatic.  The hinge lug is the same size on the speaker, automatic recorder, 
and reproducer.  It is on opposite sides, the automatic reproducer vs the 
speaker and recorder.  
 
Edison tracked with serial numbers, even his CHK weights have letters and later 
numbers stamped to ID the castings.  The first C and H weights were not stamped 
with these single digits or letters.
 
Best regards,
 
Steve
