Ive had mainly late 60s to 72 jazzes and Precision’s and I’m no expert , it’s quite difficult to exactly date a body as they stopped dating them in the early 60s, from 73 onwards they did the rout from the pickup to the control cavity , I believe they stopped the serial number on the neckplate in 76 so your large F plate with the gasket would be about right for a 77 and the neck pocket stamps look right ,around that time under the bridge I think they did the ground wire rout circular, might be worth having a look at that, the pot is stamped 77 week 11, and to me the bridge looks genuine as do the knobs
