There is no more Winslow Arms, it's been closed for a few years. The actions were from Winchester and push feed, there were some commercial Mauser but more Winchesters than Mausers, at least when I worked for them. The shop foreman was Al Albritton and the owner was Frank Martin.
Martin was a commercial airline pilot, he bought the company and moved it from FL to Camden, SC.. Al was with the company in FL. Al may have had some money in it , I am not sure, I know when Frank got out Al still had the business and moved it to a smaller building in Camden.
I was there for a while in 1977, and all the actions we built on were push feed Winchesters. There were mausers on site but I never did anything with one.I designed a classic stock that took the finer points of the ruger 77( Len Brownell) and Phil Plinkingtons classic stock and came up with a pattern for the pantograph.The Winslows were a Cali style stock, plough share pistol grip, forearm like a Harry Lawson, rollover monte carlo cheekpiece.
We had a guy running the 4 spindle pantograph, Al did the inlays and checkering, there was one other guy in the shop, I think he came from FL.
They had a lot of wood, a little walnut, great deal of screwbean mesquite, regular mesquite and varieties of maple.Coco bolo, ebony, and purple heart for inlays, grip cap and forend caps.
I didn't stay but about 4-5 months , I was driving 110 miles round trip to work there and I had on offer from another shop and moved on. I think they moved about 6 months after that.
They had 500 to 700 wood blanks on hand and I know 100-150 Douglas #1 taper bbl. The different grades of guns were determined by the ivory inlays and the decoration such as stock carving. The inlays were done by Al ,and the carving was done by a guy in FL.
I hope this has been helpful.
