Have a hunt around the forums for Logunator ( Mick Simms) he fettled a few and may be able to source or know of someone who has any spares , Some of the old one's used a cylinder that was originally the co2 cylinder from the old water/gas type fire extinguisher's so they may be a bit scarce on the ground.
The cylinder and charging adaptor should have a 7/8 UNF thread on them.
