Camera Tally Domes/ On Air Lights - seeking expressions of interest for manufacture

[austvarchive]

I've researched this over the last year or two - the tally domes on the TK60 and TK45 can be confirmed as not being simply car lenses, as with some of the PYE and english cameras.

The TK60 actually used at least two different types of tally dome mountings, one fits onto a base with like a spring arrangement, another uses a thread from the top to clamp it in place like the tk45 does, this hole and arrangement in unique to RCA.
