OK, maybe stupid question, but how do you differentiate between a 1956 or 57 S-120? I have I believe a 1957, but would like to know how to tell the difference. Thanks in advance for any info.
The serial number is the only difference, ( I believe). Ask the guys over on Oldihc.org. I found a list once that had all the years with the different numbers but I can't remember where. Posted using the Full Custom H.A.M.B. App!
