Here is another such unknown mark, L&WH in a circle. Again, maybe a distributor but maybe not as I've seen this mark for many years. Not common but common enough that it's anyone's guess.
Most that I observed were late production & in less than nice condition so it took several years of looking to find one in the shape I was looking for. This mark is on the obverse ricasso of a long model with nonmagnetic & despite the poor quality parts, doesn't show it's age.
