Hi Seaspriter,
I really like your carbine, for my money, I would add a rear hand guard, just to save my fingers from getting burnt, that's just me. By the way what is the nose cap mat'l made from cast/machined steel or a sheet stamping, thanks.
On Long Branch jungle carbines, I was personally at an auction in Ontario, with a lead gunsmith from a very famous lee Enfield Shop here. He purchased the 1944 long Branch jungle Carbine. It looked genuine to me, but I didn't have the spare cash, he got it, and it went for a good dollar. No Bodged numbers, missing markings etc, plain LB wood with no metal cap, shaped right, with all the lightening cuts and stock dia flash hider.
I have no idea how many they made, I do own a LB marked 800yd J.C. sight, so maybe they made up parts, and some got made, but there are some out there. There's also the other longbranch, lightened rifle, but I've never seen one of those. If memory serves me right, I got the sight from Marstar, over 20yrs ago, when I was just happy to have the correct type sight on my own J.Carbine.
Regards Ian
