Pin/bolt identification

Just for fun, does anybody recognize or know anything about this pin (bolt)?

DBSM ? = Das Bondage & Sadomasochism?

Well it is climbing...

I think I found another photo of the exact model. It turns out it does have an expansion mechanism.

Still unsure of the brand, I didn't think to look at the other side for some reason.

I went back and took a photo of the other side for posterity. It's branded Salewa.

I wonder whether it might stand for something like 'Das Bayerische Stahlschmiedefirma München'? Salewa were originally based in Munich and although the brand has for a long time included items of hardware I'm not certain whether or not they actually made any of it - but rather outsourced the manufacture to local engineering companies or to specialist climbing hardware manufacturers. The name Salewa derives from 'Sättel und Lederwaren', or similar - ie saddlery and leather goods - so the manufacture of hardware was clearly not their original core business; indeed I think that when they first got into mountain equipment it was with things like backpacks and ski poles - the latter, in those days, consisting substantially of wood/bamboo and leather. And I'm sure that engineering expertise wouldn't have been difficult to access in the home city of a company like 'Bayerische Motoren Werke'!

These are the type of "bolts" that were on the Compressor Route on Cerro Torre.

The Compressor Route bolts appear very similar but I don't think that they're exactly the same type or brand; they lack the slot in the end designed to accommodate a slim wedge to provide the expansion mechanism to which Austin refers - as such being interference-fit 'compression' bolts rather than the 'expansion' variety, and more usually found in hard rock-types like granite. They were also made in Italy - likely 'Cassin' brand which I think were actually manufactured by the Codega family company, better known now as CAMP. These details can be seen in this photo from Gripped magazine [and probably elsewhere] which I'm afraid I have no idea how to upload here!

That’s the one on the Nose isn’t it? 

The bolts on the Compressor Route are italian "Cassin" ones, very similar to the Sticht. 

Usually they all had a straight rectangular shaft, but it was a common modification to saw the end in for 10...15mm and use a small wedge made from 1,5 or 2mm sheeting and filed sharp a bit to give them some compression.

Yeah, at Camp IV

I haven’t seen that bolt in 17 years and recognized it immediately.
