RB 100 head style for Jon e GI

OK lads and lasies  I got a little situation here I have about 10 giant John E handwarmers and I’m looking for maybe four or five RB 100 style catalyst heads can anybody help me out there to purchase them I’ve searched on eBay and I can only find two and they are ridiculously priced it’s unbelievable highway robbery so any help would be very appreciated  I just saw a picture of the head of one of the burners on the web page where we can buy them off of our administrators awesome webpage but I don’t know if it’ll work now if we can get it rebuilt with the catalysts, of John’s webpage that would be perfect  and would the round headed zippo one work for Jon-E  GI  warmers   I put a picture of it on Google plus if you can find it thanks all the same come to Mexico for a week will return what I can still keep in touch when I bring Miss handy little phone with me

Eamon,

Can you measure the dimensions of the Jon-e head with a pair of digital calipers and post them here? More likely to get help that way.

Will do thank you
