I was given a 1950's E2 Rolleiflex like that, actually it was almost non functional as the owner had only put about 6 films through it from new, then continued to used his Minolta Autocord, all the lubrication had dried up. The lubricants had dried out.
Now after a CLA/Service I use it sparingly, it's in near mint condition and I'd like to keep it that way
I now mostly use another Rolleiflex - an Automat bought later at a a real bargain price at a flea market as it's not so precious, that's here in the UK - in Turkey it's a Yashicamat 124.
It depends how equipment is given, I'd like to pass it on again after some use making excellent images, but not worn out
