Hi Guys, many many thanks for the replies.
The red paint was on the underside of the front hand guard / stock, woodwork. It would have been plain to see until someone painted over it with green, in that position it would of course been plain to see in a rack. The strangest part was the pattern left by the glue residue that resembles a scull and cross bones, unfortunately I've been 'cleaning' and removed both the glue and the green paint. It came off easily with spray oil. I also wonder why it was not destroyed if it was BR-PC. Maybe the woodwork was saved for spares? The only major fault I can find is that the stock is loose, but this could be tightened. I must admit I'm not sure how to add pictures, they are in gallery 847 Mk5 Lee Enfield, not sure how to move them to the reply, (I know, typical squaddie, has to take his boots off to count over ten,)
I'd hate to see this old girl relegated to a 'wall hanger', she obviously worked hard so deserves better! I guess I will need to spend a little extra on her.
Once again many thanks for all your help.
Mike
