I did a fully skeletonised L9 pistol for the SASC at Warminster using the machinery in the old Bedford machinery truck. It replaced an old hotch-potch thing that never worked properly and was useless for anything. Because the people who did iin the 50's didn't realise that certain parts had to remain in contact throughout its recoil and run-out phases. It is still there. I did a lot of others too that were given away as presentation pieces
