1920's Sterlingworths.... subgauge

[dennyibrandt]

I have had a number of these, all with a nickel old coin look to the receiver. Do ALL the 20's subgauges have chromox receivers or just most of them?.......DEN

[bbman3]

Denny I have had several smallbores and it is about equal between Chromox and some call them Krupp steel frames. Bobby

[dennyibrandt]

Thanks Bobby....McIntosh said about half were Chromox up to WW1 and nothing was said about after WW1. Wouldn't the existing inventory of Krupps dwindle away after the war and leave Chromox to dominate the 20's?......DEN.

I've never seen any reference material that indicates or implies that pre-Chromox frame forgings were made of Krupp steel. Early Fox adverts pumped up its use of "genuine" Krupp steel for graded barrels, and that the cocking slide/lug and other critical parts were made of chromium-nickel alloy steel. If Fox had been using Krupp steel for frame forgings I'm pretty sure the Fox marketing folks would have made a big deal of that in adverts etc. Net, I think that pre-Chromox frames may be considered to be mild/low carbon steel.

Roger that Silvers!

Krupp produced a fine nickel steel which had a high ultimate tensile strength, high yield, and that would endure a lot of cycles. It had very desirable qualities for barrels but there would be be no economic sense to buy that for actions.

I imagine Krupp produced a lot of mild steel also but that was certainly available domestically.

Thanks guys.....So...Is it fair to say that whatever the non-Chromox receivers were made of, WW1 reduced its availability and most of the 20's receivers were Chromox?...DEN

[mark beasland]

Were the actions advertised as made from Chromox?

The house I grew up in, built in 1948, has Krupp sewer pipe in the crawl space. Krupp is embossed right on each section if pipe.

[abner]

What gauge????

[dennyibrandt]

Didn' t think it made difference but my question refers to 16ga.......DEN

[Fin2Feather]

I think Abner was asking about the sewer pipes .

[mark beasland]

Let me post the question in a different way. I am not a Fox expert but it has been my understanding that Krupp, Chromox and Sterlingworth Compressed were marketing names of barrel steels, actions were forged of mild steel and case hardened for surface hardness and corrosion resistance. Is there any evidence in writing that I am wrong on what I thought I knew?

Respectfully.

Mark.....Page 137 of McIntosh......"an entirely new steel, known as Chromox High Pressure Fluid Steel, which will be used exclusively by us in both 16 and 20 gauge barrels and frames"......from the early small bore brochure....DEN
