By the way, I pulled all lights this past week and found two things about the fixtures. First, all but the Kliegl #1365 had a 6x9 or perhaps a bid wider focus PC
lens. Unless another source has step lenses in their 807, 7A (as new version found), or #1700 LECO lights, they are all PC lenses in them.
Also, it would seem there was a choice of P-22s (
Bi-Pin) or P-28s (Medium
Pre-focus) for lamp type during the at least early 60's versions of the #1700 series. Of thirteen lamp caps brought home last week, five were P-28s, the others G-22. (Like the G-22 type of
socket also though more effected by heat in some ways.) The P-28s lamp sockets had the newer X-slot cooling vent design, the older ones were a
bit more tall and used for all intensive purposes the #807 hole
pattern for cooling.
Also found in the collection is three fixtures with the exact same
lamp cap - all with a P-28s lamp
socket. So simialr, I cannot tell who made which
lamp cap. Of the other fixtures were two Kliegl #1365E as similar to the one already in collection, two
Hub #8764 with PC
lens and six unknown but similar to both fixtures that the more I work on are possibly the first
Altman fixture, or perhaps Century. Almost all knobs/parts on them are the ones
Altman used in the 360 series, yet it's for all intensive purposes a Kliegl design. Derek will soon be getting one to study and ask further questions about.
