I have a Perkins Midi Mate Cooker,circa 1976.It is a vaporising type of burner,made of Stainless throughout,has 3 hob plates 1 oven and it heats water via a colorifier,that came with a pressure vessel test cert.I have had it running in my workshop,2 rads it runs Toasty.Never seen another one,it came out of a fishing boatIts about 2ft deep 3ft long . I was hoping to use it in my next project,but I dont think I will ever get the time,Iam now 74 yrs old and got more projects than I will ever get round to! The Wife keeps finding me things to do!
