Judging ONLY from the pictures posted by Jim88, that case coloring doesn't look right; it looks more like a blued receiver that has been rusted, then oiled. The lever and hammer appear to be color case hardened, which would be correct.

Buffalo, any chance of seeing your Photoshop product?

I believe the patent date "on the muzzle" is actually on the magazine tube latch; that is the last (and most common) of several tube latches used on the Model 1892 and 1894 so the tube could be pulled out to let the barrel turn without having to remove the magazine plug and drive out the retainer pin.
