yes, this was a horn trigger guard, I will look for a similar piece here so you know how it looks.
please release the firing pin assembly and make a pic of it, I suspect it will be no big deal if one pin is broken (its a needle).

do you wish to restore this gun? its possible with patience.
what it is now can become only better with some work. the original shape is so much damaged it don't hurt anymore.
we can make it a long time online support project.
