I have an 1896 Krag Carbine that has been sporterized.

The stock has been modified, the rear sight has been removed & a peep sight & scope were added. (Probably a long time ago.)

Since an original rear sight is too expensive for my budget, I thought I'd be able to find a reproduction but no such luck.

Would any of you have a source for a reproduction rear sight?

I do have some background in machining. I should be able to make one.
Would any of you be able to supply me with dimensions for the rear sight? (Length, Width & Height would be great.)
