TK Skull - Info Please

[Stepdale]

Hello,
A friend of mine just picked this up out of the woodwork. It looks like a nice early one to me. Just wanted to see if anyone could give any info as to time period of manufacture, type of cap it would go on, etc.
Thank you,
Dale

That's a very nice Deschler skull, made of CupAl I believe.
It would fit both Alg. caps and WSS caps. It's not the earliest version.

Thank you Anders. He'll be glad as he wanted it for his WSS cap.
