EK2 marked with an A or H

[ww2collector]

Hi guy's,

I bought an EK2 and the ring has got an A or H not super clear
but for sure not a number.

What could that mean as far as the maker concerns?

Sorry no pic I broke my camera.

Thanks,
Eric

It is most likely a '4', which would indicate manufactured by Steinhauer & Luck

Difficult without a pic, but I think Harry is onto something there. I have seen a couple of S&L 4's that looked like h's
