When purchased new

[Edward Tinker]

the only aftermarket item you'll find is holsters - now boxes - rare as hens teeth -

you see ones like this

and sometimes a Stoeger with DWM, but i Have also seen DWM boxes - I think most weren't shipped in them, or you'd see them more often. But then I have never seen a Colt SSA box?
I have seen lots of early 1920 era boxes for S&W and Colt but earlier is hard to find.
