The top for the O N R and S are all the same top and when new the R and S top
would fit in the large carriage. If you look at an R or S you will see the
notch for the large carriage centering pin.
When the dome tops came out Edison made them universal so they could be used
for any reproducer, an O R N or S.
Edison drilled and tapped three holes in the R and S tops, he used 1-64 threads
the same as the large hinge block studs.
The R and S have their own serial numbers, the O and N have their own serial
numbers. When the O came out it was alone until around 22,000 when the N
joined in. The R started out alone and around 13,330 the S joined in.
The first R reproducers have a nickel plated brass bottom or shoe adapter. The
later ones have a pot metal shoe adapter, but the nickel plated brass shoe
adapter is found on the latest R and S reproducers sporadically as Edison
always has an intermix, especially during the end run.
By June 1913 the R and S was obsolete so Edison used up the tops stamped with R
and S serial numbers to make the N-56 reproducer.
The N-56 appeared in the 70,000 range in the O and N serial numbers, it is
found with 31,000 R and S serial numbers as well.
Thomas A Edison Inc. appears by 13377 on the R and by 26237 on the O.
The R and S have all the different pot metal tops, the flat top that says Nat'l
Phono Co, flat top that says TAE inc, the indented letter dome top and the
raised letter dome top.
