100-200 counts per minute TTL Dose

This is the first version TTL for the Pentax 6x7. Usually identified by the wide silver border around the name plate and not the thin line of silver. The version I have is the "Honeywell" and it is the one throw 'ON' switch. All parts are original, so no swapping of parts...oem. I would guess that the "ocular" element had to be of a high refractive index and so Thorium was used. Subsequent versions were post ban.
