Hi Ian,

Compur #0 with 105 Tominon never had a f/scale... salvaged shutter (from??)

Copal #0 with 150mm G-Claron has a f/6.8-45 scale with no other markings

Compur #1 with 210mm Commercial Astragon has a dual scale f-5.6/12 (from convertible Symmar??)

Copal #1 with 210mm f/6.8 Caltar II-E never had a f/scale... salvaged shutter (MP-3 35mm??... not the right markings for MP-4)
