Its on a 45 chassis, and I see the origional lamphouse&condenser sitting on the baseboard, along with what I assume to be the power supply for the retrofit head. I won't get a real look at it for a week, but I'd like to have an idea.
Do a Google Image search on Ilford multigrade 500 - you can see it is the same. Not sure what other bits are supposed to come with it though - I think it needs a control unit as well as the power supply. Someone here will have one...
