Geezer vs Lens

[Taneli]

Was looking for old Black Sabbath pics when stumbling upon this one, is it a lens Geezer holding?!

I think it might be an ash tray.

A M42 thread lens? 135mm?

 

[drd1135]

A lens being used as an ashtray?

 

[mnhoj]

A lens ashtray double timing as a whiskey shooter?

...yes, lens ash tray looks fitting
