Shawn, I always thought it was 1902 to 1904, but it was actually 1901 to 1904 I appreciate Allen letting us know the month. I examined one of the records I have from 1904 and it appears to be just as thin. I probably have at least 20 of these, the ribs are very thick. I have also noted that intermittently from around 10100 to 10400 the wax ambero wax 2 minute records appear. Are there more than three 2 minue wax formulas, the early no rim one, the one with rim and the wax amberol wax? The 2 minute Wax Amberol Wax records I have are 8708 with a Patd 26, (and the 26 is light like the catalog number on the 1901 to 1904 records with no titles) 10120, 10146, 10262, 10278, 10303 .3 & ..6, 10374, 10377, 10395, and 10400. The 17 records I have from 104xx to 10562 are all the regular wax. As always I really appreciate your replies. With regards to the brown wax blanks I have one that came in a box dated 1914, was the formula different on these? It is a yellow box and I have seen some of these later boxes with an ICS machine.
