SWB maker?

[Stepdale]

Hello,
With the permission of the seller, I am posting these photos of a SWB he is selling. I have searched this forum and another one, but haven't been able to find an example like this one, so wanted to see what some of the WB experts have to say. It has no discernable maker marks. I have asked the seller to place it on hold for me until it is reviewed.
Thank you,
Dale

It´s a L/24

Thank you Hans! I believe I do see a bit of the maker's mark sticking out now from behind the pin.
