Hello. I am building my own lab at home again, after 20 years away from film. A good friend gave me a Meopta 6a head without the column, and now I need to buy it separately, something that seems quite difficult. Found online a Meopta 5 enlarger very cheap (15€) one hour by car from home. The head will probably be damaged but the column seems to be fine. My question is: Does anybody know if the opemus 6a head will fit in the Op. 5 column? If so, I will spend the time to go for it. Thank you.
