I agree with Bobby, the Brass No 00's can be had for between 60.00 and 80.00, but generally sell for 125.00 to 150.00. It would help if you could post a picture or click on the envelope next to my user name to email me a picture to post for you. I've never seen a Hot Blast No 00 in Brass, so I'm assuming it's a Cold Blast. Most of the Brass Cold Blast No 00's I've seen were the later ones with the side lift. The early Brass Cold Blast No 00's with the lifter through the fount are very rare. The Hot Blast No 00's I've seen have no lifter at all.

The much later Gem lanterns came in at least five variations, all have side lifts, some inside the side tube and some outside the side tube.
