Mine aren't nearly that intricate.
I have close to a dozen Martini type rifles, chambered in military stocked, 577-450/303Brit (enfield/Metford rifling), 357Maximum,7x65R, 225Win, 218Bee, 30-40Krag etc.
Three are in various stages of the build from all parts gathered to needing stocks.
The 30-40Krag has a .308 bore and it's a very accurate, nice handling rifle.
Martini type platforms aren't for everyone. Some folks find them to be awkward and clumsy. You either love them or you don't.
They're a very stable platform and stock fit is extremely important. Fitting scopes can be a real chore, if you don't want to drill and tap the side of the receiver.
Making up custom barrel fittings to accept scopes can be tedious at best.
Getting a rib fitted, expensive, so are the express sights. Not only that, if the job isn't done properly?????????
I really like Martini type rifles.
I sold a Swiss custom made, traditionally stocked for off hand shooting, Scheutzen rifle, chambered for 8x46R and fitted with beautiful, adjustalbe rear tang mounted sights and an enclosed front sight.
I miss that rifle but my eyes, even with glasses could no longer do the rifle justice at the range.
The fellow that is taking care of it now, has it displayed in his den and never intends to shoot it.
