This sale is for a Mamiya 645 Pro 120 back HA401 for the Mamiya 645 Super, Pro and ProTL cameras; it is in really excellent condition and perfect working order.
This back has only normal very minor signs of use – the usual light scuffs that these backs always seem to pick up – and it works perfectly, including metering correctly with an AE prism (and a lot of the backs on eBay are faulty and will not let you meter with them – but I always test for this). The 120 insert is in near mint condition with minimal signs of use; it is actually a 220 insert that has been converted to 120, but works perfectly with 120 film. It cannot be used with 220 film.
A great addition for your Mamiya 645 outfit – you can never have too many backs! 120 insert and darkslide included.
