Vintage co2 pump cage

[19charliesangel61]

Hi out there, I am looking for a rather obscure co2 pump cage (holder) which was produced by Milremo in the 50's/60s. They were a skeletal wire frame about 30mm diameter and approx 220mm in length and were used by the racing boys and were usually fitted either on the underside of the down tube or alternatively behind the seat tube in the same way that the rather more familiar Pennine co2 was fitted. So if anyone has one kicking about it their odds and ends box then please get in touch.
Cheers.

Nitrogen gas went into those large canisters.

Just out of interest, why has the bike in the photo got a co2 cartridge inflator and a conventional pump?

Probably because being quite a few years old, it's not in working order and just for show - nice to have but not very useful! My Ellis Briggs has a non-working Pennine Co2 pump.......looks the part, but I have a modern gas inflator in my jersey pocket!

The CO2 canisters in the Pennine pump hold significantly less (8g) than is needed to get to normal riding pressure. So the pump may have been for getting the tube up to a low pressure and then finishing it off with the CO2.
I have both versions of the Pennine pumps and they are a conversation piece at our coffee stops.
The nitrogen canisters, according to the Classic Lightweights site, "had to be sent back to Kitching to be refilled". With their extra weight and the specialised refilling system made them less attractive to the Pennine (and Lytaloy) CO2 pumps which used readily available CO2 bulbs sold for soda syphons.
