I hate seeing Rs shirts in a charity shop.
I have an old long sleeved 'Clubhouse' home shirt to give away - it's x-large - 46/48" (these days I'm a 40"). It's a bit rare as no sponsor on the front (would have been CSF or Compaq at this time). It's not been worn for donkeys years, just given it a wash to make sure no moths lurking.
If anyone wants it drop me a reply, can post or bring to the Brainfart game.
