First off , I'm new here, wanted to say hello to everyone,hope everyone is well . Last year I purchased a "1977 stratocaster" on local CL off a local guitar dealer who specializes in high end Gibson LP reissues . I did purchase it at what I thought was a fair price for a late 70's strat with a OHSC even though it weighed 10lbs. It is in nice condition with low miles, nice straight maple neck .. i believed it to be a 1977 since the the neck decal has a S7 serial # and was informed it 's pot codes were 1977 by the seller. After a couple weeks my curiousity got the best of me and i removed the pickguard assembly. He was right , the bottom tone pot had a '77 date , the others i couldn't read from solder drops. It also had a a 3 way switch, i had read Fender started using 5 ways that year. The p/u codes were hard to read but they looked like they had '78 dates.On the bottom of the pickguard was a factory Fender serial sicker with a S9xxxxx serial #, so I have a strat with two serial numbers that don't match. The bridge , tuners , tremelo arm , neck plate ,etc all looked period correct. I felt like i had been had somewhat , So to me the 1977 Antiqua didn't really seem to be true after all. At this point I'm thinking of selling,I just don't know what to date it as ...a 1977-9? Would anyone like to weigh in when you get a chance? thanks D.
