I have never seen a 20 pounder anything for sale in the US before, so I had to have it. I recognize the No. 221 time fuse is the proper one for a 25 pounder smoke round, so I assume this is the correct fuse for this round? I paid $400 for it with shipping included, and I think I got a bargain. Do any of our UK members have any spare smoke pots to go into it?
