You're welcome.


The construction seems a bit cheap compared to the usual ones your
comments led me to find. The cartridges are clipped to the board and
connected by push-fit or screw/olive pipe connectors. It does work
well though because I remember it being used.

Most units these days use 8mm pushfit pipes between the cartridges.

I think your only chance of getting parts will be if it uses standard
sized carts, 8" or 10".
