Recently got a 57 duo jet. Same as George H owned. Which bigsby for this guitar please. I am sure Harrison's v cut bigsby is a later version? 58/59? Is it the 55 version? Also It has a 50 s rocking bar bridge should it be a melita or rocking bar with the bigsby? Thanks

A B3 would be correct. The bridge, I'm not so sure about, but I believe the bar bridge came out in '57.

The good news for you is that Harrison's had the V cut, and that is a later version--1960 and on. BUT, what sucks for you is that I believe it's the version with the phillips head screw on the arm. (I can confirm this when my wife is around with that Harrison guitar collection app she bought me that's on her iphone)

I've always wanted to see is what the hinge on a V cut B3 looked like back then and if that is unique to that time period (as the hinge was on the early B6 v cuts) then you have your work really cut out for you.

Here's a period correct Bigsby on my brother's 56 Jet Firebird. It's not original to the guitar (the extra holes bespeak that) but it was added when the guitar was new.

I also pointed my brother to the last of the pre-v cut B3s (phillips head) when there was one on ebay a number of months ago. The seller conveniently listed it as a B6 and so we got it for not an extortionate amount thanks to that error.

Ok many thanks for this info. basically its the same unit as on my 55 silver jet only without the fixed arm........

The Duane Eddy arm in lieu of the fixed one.

OK Thanks, can it be a four hole screw hinge or a 3 hole screw hinge bigsby b3? seems to be two versions of the b3?

For a 56 B3, it will be a hinge unique to that Bigsby--this is that same 56 Jet Firebird.

The second pic is a Selmer UK "US Patent" Bigsby B3 I picked up last year. It has the same hinge (I drilled new holes to match the G Tailpiece ones).

I've not seen an early V-cut B3 in person (which would have the phillips screw like my Selmer B3 as you can see) which is why I mentioned that above. It would be nice to see a pic of one.
