I thought the Metoform's were originally for Rapid Access materials, Agfa nand Ilford used to make Rapido print and Ilfoprint and these were developer incorporated just needing an actvator and stabiliser.

Early Ilfospeed was also developer incorporated and could use the same Rapid Access machines someting Ilford kept quiet about at the time, This one may be a later model a bit like the Ilfospeed machines which used developer and fixer. It's unlikely to be any good for RA-4 as it may not be capable of the 38C temperature needed and the dev time may also be too short.
