Flame or not, but there is a reason for coatings... The lenses itself may have some sharpness between okay and wow, just don't expect miracles when taking pictures with some front- or sidelight involved ^_^
Find out how much they are worth today, sell one and pay the adapter for the other three (I mean, 35, 40 and 50 mm are pretty close...)

For their time they were very fast and sharp, so instead of pay thousands for Meyer optic, throw some bucks to the adapter and find out what or if you like it.
