Don't think so. We (a number of knowledgeable collectors) have determined that it started life as a New Model Army and at some later date between when it was originally made up to around WW2, (The previous owner has had it for 70 or so years) some gunsmith with a lot of time on his hands did an overly complicated cartridge conversion on it. I have detailed pictures of the work. Here's a link to some of it.

BTW, I meant to add that somewhere I have heard that there is some question if Remington ever actually filled that Egyptian order. (I'll have to dig through my references and see ifI can find where......)
