It does seem very likely that this was from the Fuji-Gen-Gakki factory. May have been Ibanez, Greco, whatever but they’re all similar. Any other info/pics? Bolt on neck? Convincing toasters?

i think you are looking for Fernandes not Fernandez, Feranades did indeed make good jap copies in the mid-late 70’s and early eighties, i know they did some pretty good strat copies, but the best copy at that time was by Tokai, who i know made a good copy Rickenbacker, they did a convincing 2 pickup 360 model, and i think they also did the lennon type 325 complete with white scratchplate, that ‘Rickenbacker’ truss rod cover you talk about is still available as a replacemet spare from Rickenbacker, and they now ask for evidence of the broken one or evidence or ownership before selling one, which has now of course sparked a ‘black market’ in Ricky truss rod covers, enter ebay.com
