Yes, that's true. The kits in the squadron stores had the BCB saws (along with other curious things including fishing kits, 'matchless fire kits', and massive magnifying glasses!) in these black PVC canvas wallets. I went on a couple of courses where we were issued out kits at the start from the survival schools in Newquay and elsewhere, and they had the BCB saws too. That said, i am assuming they were BCB branded - they looked identical to the saws that i had purchased myself that were all BCB. On one of the courses we were all supposed to make bow saws out of a bent bit of hazel and the issue wire saws. I seem to recall that many didn't even take the tension of the wood and broke then and there. Most of the rest just snapped when they were used (mine always let go where the bit of crimped metal holds the braided wire to the rings/handle).
