A new kid on the block

Hi, I live in Cornwall, UK. I'm retired and am resurrecting my interest in stamps that I was last involved with 30+ years ago. At that time I was a teacher and during a couple of lunchbreaks each week ran a stamp club with the kids where they could help themselves to stamps that I kept in a couple of boxes. I recently met a chap who has Asperger's syndrome, lives by himself and has been bored rigid by the lockdown and not meeting people. I asked if he would like to sort through the boxes of stamps that I still had and make them up into packets for sale at charity shops to raise funds, he said that he would. I sorted through the boxes and found odds and ends that I'd forgotten about, one of which was a Morely - Bright watermark detector which had dry dye sacks. It was while I was searching online for replacement sacks that I was patched through to this site and found it both friendly and interesting
