Thanks, that site is very informative. It still doesn't list any info as to the single or double perf that I am aware of. If anyone has any more input I would appreciate it.

I have been given a Bolex H16 non-Reflex (early with the the circular mount) It looks as if it takes double perf. serial **317 anyone know if it runs single or double perf and what is the easiest way to tell.
