An early 1970's Wilesco D28 has for sale , I did some cleaning on the boiler , inside and out .the boiler was actually very clean inside , after a short white vinegar bath , very little debris was captured (with a coffee filter) from the inside contents , must have been stored well. I received it from the nephew (he was 73 yrs old) who's uncle bought it all brand new. I replaced a few worn/cracked 0 rings in the throttle & drain valve & gave her a run. the heater is listed @ 600W but was actually putting out 770W. it is in overall very good condition. These are often mistaken for the D24 which is smaller, the D28 has a larger boiler (4 holes in the base) and it has a 2 tiered platform that the engine sits on vs.. the D24 engine which sits directly on the base plate. $600 + 30 (USA) shipping (its big)
PM me if interested.
