I bought a set of BPM bellows when I first started out...and there was something quite cool about getting these English built items by mail order from a small manufacturer in Brighton. I stumbled upon them again in the 90s when I bought a second hand Illumitran. I decided to become a collector and acquired just about every mount made, along with all versions of the bellows, and instruction manuals and sales brochures/price lists. I decided to build a site to showcase that, and sell off the collection which I realised was taking up too much room and unnecessary.
