I'm led to believe it is about 40 years old. I can't find it anywhere yet and there are no serial numbers.seriously tho, ive searched for that logo and cant find a thing. I wonder if its a custom built jobby?
Gretch use branded Bigsbys which is why I'm sure it isn't one of theirsI thought the same (the 'G' on the tail). Cal will have a good idea if it's a custom built thing. Good luck taking it apart and if you find 'Made in China' give it straight back to your mate.
