Got one myself John, I intended to graft part of a spare body on the part that Geoff had machined off........ its still in the back of a cabinet.............., lovely rifle but as its been said before, its an example of what not to do with a No4T.
I sold the (Brindles) sight some time back (Mick will give you the run down on where the name of the sight originates). I'd started to make a scope bracket on one of the ships I was on and also a chassis system for it so I could use a set of AW stock panels.
Unfortunately they went AWOL when I moved ship, (I did have a lot of projects onboard) including a **** ***........... anyway back to L42, I'm on the look out for a IWS sight if you come across one.
