Added two new lamps to the stack today: a Tilley x246b and a Hipolito H202. I read some threads about the effect over-pressurisation has on the fount. The bottom of the tilley has a small bulge in the centre so I'm a bit afraid my fount is worthless now. Does anyone have a photo of a certified ballooned 246b tank? The H202 has a nice bonus. After settling with the seller for the Tilley he said he also had a small Hipolito lamp available. NOS with all the accessories. For cheap as well. Unfortunately upon collecting the lamps i found out the lamp was not new but at least it was complete. So got a nice discount and I took it as well. Nice thing was it came with a letter (dated November 1995) from the previous owner (Dutch fire brigade) with some useful tips and precautions about using this lamp. Apparently they sold off this lamp in a big batch of other surplus materials.
