If you want to double your money, I think I know someone who would be interested (me).
Great deal, there. You did good. To my feeble little mind, I think the true .54 caliber is a big plus. Not a big deal, just a big plus. by the time the re-issue of the rifle happened, I had stopped dealing in the import guns and was pretty much just doing accessories. I do recall that the original run of rifles was browned, as the first one I got appeared to be about .22 caliber due to the fact they had not stopped the browning process. So, maybe the later ones were blued. Dunno.
I really don't recall which came first, Western Arms or Allen Firearms. Doesn't matter as it was all the same guy, Leonard Allen. I think I recall that Western Arms might have been first as it was a collaboration between Allen and someone else when he was in California, and for some reason I am thinking it might have had something to with EMF (Early and Modern Firearms Co.). Maybe.
