Iíve had an 18Ē Wadkin Bursgreen under and over bought here in Sydney.
It was a good machine had it for about ten years in a 4 person workshop.
Only problem was extraction. It was from a Pattern shop so not beaten to death on hard stuff.
Also bought and sold a 24Ē RM from another pattern shop.
My point being they may be available in Oz and may not need rebuilding.
Doing this on my phone so might post more later.
