1970 would be way off. You can't leave the R in front of the number off. This was during a time when Selmer outsourced manufacturers, Czech, German and American. My research leads me to assume that those with RXXXX were most likely made in the 30's, whereas the serial numbers with 5 numbers after the R were probably made in the 40's. Since records are virtually non-existent, this can only be considered guesswork. Until we brass collectors pool our resources on the subject, we can only go by design of horn, case, and possibly included mouth piece and papers. I have read that some of the 'Manhattans' did NOT have the R in front, so possibly those had a different manufacturer.
A Selmer trumpet with a serial number of 43417 was made in 1950, so as of 2013 it is 63 years old. All Selmer trumpets have a serial number and there is a chart that shows what year the trumpet was made.
According to Selmer's website 1952
Selmer's website has a comprehensive list of years versus serial numbers. You can check it out yourself at the link below this box. But your's falls between 1947 and 48
A serial number is the best way to verify how old a Selmer Signet Soloist trumpet is. As a general rule, these horns were first made in the late 1960s, around 1967 to 1969.
Best estimates put this trumpet as being manufactured after 1998.
