Yeah, I know, post pictures. UNABLE TO, sorry.
Only research material I have is Temple and Skennertons TREATISE on the BRITISH MILITARY MARTINI and this only gives a paragraph on this maker.

The other two large receiver Martini's I have are a full blooded carbine, IC1 1884 s/n 387, and a 1872 II Rifle converted in 1899 to ME 303 II over I, S/N 10043? 7572

OK, you lot are too slow, looked it up myself, Henry Rifled Barrel Co. now what about the rest?

Since you had the books right in front of you and looked it up your self you probably learned a lot more than if one of us just type Henry rifle barrel.

Besides I have been off to college and internet play time is limited.

Yeah, big problem is that this book is very difficult to understand, have since picked up a couple of other reference volumes and am wading through them.
But this forum often brings to light things that are often overlooked.

All forums are helpful, this one is a bit less martini active than others. The Treatise is the best most detailed book on the Martini you will find.
