Brass Monkey 2

Designed by Steve Nicholls and Ali Morris, purchases 2019.
(7 brass cylinders, where two go together to make a total of 6 cylinders, each 2.75" long)

A combination of a trick take-apart puzzle and a 6-piece burr. Looks like a 6-piece burr when assembled, but it is actually 7 pieces where half of the key piece unscrews (not a burr move). The other half of the key piece is held in by a pin so it does not fall out and is not the first piece to be removed (not a standard burr feature). Here are photos of the puzzle being assembled:
