Message #1 Posted by Michel Beaulieu on 30 Oct 2003, 7:37 p.m.

I opened my 34C and my 37E and when reinstalling on the 2 calculators, i realize that i don't know which cover goes on wich calculator...

One cover has "Made in USA" and the other one has a serial number 2027s35507 "made in Singapore"... ... Same color, same size, same scratches ;-(...

Thanks Michel

All three of my 34C's, with serial numbers corresponding to 1980, 1981, and 1982 were made in Singapore. Yours is a 1980 model.

Michel, I have a 34C the back of which says it's made in USA and that the serial number starts with 19, which puts its manufacture year at 1979. What are the first two digits of the serial number on the made in USA half case? According to this museum's pages, the earliest sighted 37E serial number starts with 1850 whereas the earliest 34C starts with 1928. Hopefully, this can help you.

If not, ask again on this forum if anyone knows when the 34C and 37E respectively had shifted production from the US to Singapore.

Have you tried looking for scratches, marks, stains or anything that could allow an association between top and bottom halves ?
