I first started selling vintage cameras in Camden Town, London in 1981, then moved to Portobello Rd in 1985, where I started adding scientific instruments to my stock. I also exhibited at the Scientific Instrument Fair in London in the 1990's, but left the UK to live in Southern France in the year 2000. I started trading again in 2009, and since then I have been sourcing items in France and UK for clients here in Perpignan and back in UK.

I have one or two items for sale on my website www.junk-cellar.com
