[Bruce P Bruner]

I was searching 45-75 Winchester on GB and ran across this vintage box (around the turn of the century) with Chas Parker hand written on the box. Item number 931634684. I just thought perhaps the Parker Bros folks may find this of historical interest. I have no affiliation with the auction nor will I be bidding, as I have a plentiful amount, some hand loads illustrated (third photo). The last photo is my Uberti reproduction.
The 45-75 cartridge (bottle neck) was developed for the big brother of the 1873 Winchester, the 1876 Winchester, known as the "Centennial Rifle".
