I'm still seeing the type that will work with standard threaded canisters on eBay. These are not Brunton, though. Quality? I can't say one way or the other..
Looked like the other Jim had an actual Brunton one for you, yes? If so, then you're set. Otherwise, if you become a member here, you could put a "WTB" (want to buy) notice on the Gear Swap, or you could try eBay.
