Hi guys, New member here and I'm hoping you guys can help. I bought an 86 fender strat over the weekend. It's one of the F series that have the ST 357v stamped in the neck. I believe that these were used in some squiers of the same era. The neck is fine and is stamped, but I am concerned about the body as there is no stamp in the neck pocket. This seems unlikely for the way they did them at the time and I wonder if anyone can tell me if I've ended up with a partscaster? I've included pictures. If there is any other advice you could give on what to look for I'd be really grateful. The pickguard has been changed from stock and when I took it off there were no markings inside. I do really like the way it plays. Just want to know if it is totally genuine. Thanks!
