Good to know you are still around and retired.
Your catalogues etc were very useful and I bought a lot of Polysales items from them and found the Polysales mail order service to be excellent. In fact I still have two have those filter funnels you produced (a red and blue) and I still use them for all my film processing! They must have been the best photographic buy I ever made with 40 odd years of use and still going strong.
All the best,
The aim of art is to represent not the outward appearance of things, but their inward significance.
