It contains some small flemish glass. I don’t have time to extract these but if you want to come over you can do so for the following prices:
Three pieces of small flemish in size 111 x 280mm: £10 each.
Six pieces of small flemish in size 83 x 280mm: £7 each
It contains other bits of nice glass I will sell as spare parts if interested. Will take better photos if I get time!
