A Kodacraft Roll film tank (looks like
this, except mine needs cleaning) was my first developing tank. It uses a very easy to use apron to hold the film. It's biggest advantage is that it's very easy for someone young or with impair motor skills to use. I once knew someone with Parkinson's; this was the only tank he could manage.
Mine is dirty, but I don't see any cracks. Has a 120/620 apron. It has a makeshift cap (not the grey top) to allow for inversion. The grey top is slightly loose, but still usable. The steel plate to hold the apron down is included.
