1914 DWM

As I said on the other thread for this gun, too pronounced, too even/regular, too well-defined. The edges of them should fade away more gradually, and they just look too darned big. If they can be made to appear more "normal" with different lighting, I might be happier with them. I know that flash can cause some weird effects when photographing surface finish...

I lost the other thread, but IIRC it had a reference/pic of a Bohler Bo30 barrel as well as a Bo32...I believe these indicate different steel alloys, but I don't have a reference that lists the composition of Bohler-named steels. But they would respond differently.

Alloys are interesting. If you make and name a certain alloy and copyright the name, then anyone who markets their steel and uses your name has to pay you a royalty. CPM154, 530V, and BG-42 are all good examples (all used in knife blades). In England, Reynolds 531 is a common structural alloy for race cars. You can make the steel/alloy and even sell it, but not use another mfg's brandname. I actually buy my steel, aluminum, copper, and Delrin [there's another brandname!] from a Krupp subsidiary, and they are careful not to infringe on other makers brandnames...

...But I digress...

The Böhler number does not indicate a different alloy, it's the hardness number on the Böhler Scale, a proprietary system similar to the more familiar Rockwell Scale.

Thanks for the correction Norm!

I still think that the physical appearance would be different between the two, as regards to bluing and aging.
