HTN spacer ring for Sankor Compact Cinemascope / Sankor Anamo-Prime

This is a spacer-ring to make the HTN ring (https://www.facebook.com/HTNanamorphic/) work on the SCC or SAP.
Without it, there's a gap between the front block and the HTN ring, resulting in non-locked focus.

It's really just a small plastic ring, goes on top of the lens and under the HTN, it's that basic :)
