I have just bought a guitar with Rellog Gitona pick ups and Fenton Weill vibrato arm from ebay (haven’t received it yet tho!).
It caught my fancy, because I collect a lot of early Hofner guitars. But after searching for more details on the internet I saw your page with the Alexis Korner & Cyril Davis photo (the guitar looks exactly the same with original 2 plug cord).
Do you have any further details?
