This is a Vintage MPP (Micro Precision Products) 120 roll film back for 5 x 4 cameras. Made in the UK.
In great clean working condition. Dark slide moves easily, though it could do with a clean. Interior is in near-mint condition.
I am clearing the last of our pro-studio gear. See my other listings for lenses, filters, kit, camera backs …
All in working order – happy to refund if you’re not happy.
