The sheer crudeness of this piece should be the very first thing that smacks you right in the eye.
I've never seen any kind of a patchbox on a Musketoon [note spelling], either, unless it's intended to be a cap holder.
Come to think of it, I've never seen one of those either.
Given that the real thing was one of the first mass-produced interchangeable component firearms in service, you should, in theory, be able to remove every part and replace it with that of a genuine Enfield-built model. I can't do that, but what I CAN do, to while away the odd hour or so, is to blow up the pics to the same scale as my genuine item and see what fits.
As you may have guessed - nothing fits.
Anywhere.
The trigger guard should have a front extension with a special screw stud that takes a small chain to hold the nipple protector - should be all brass, too, as is usually the rule for the other furniture. The left-hand side should have two fixing screws in collars. The EIC look to have been put there using bicycle frame ID stamps, and the VR, not only too small, but un-serifed. The ramrod has the wrong terminal, the barrel bands have the wrong spacing, and the lack of proof marks [are there any anywhere that we can't see?] yet another giveaway.
That's at a quick look.
Khyber Pass frawk, Sir.
