Hi Mike, Al & Paul..
Mike i will have a rumage around and see if i can dig out the manual, just having probs with the naff new Wifi printer/scanner so may take a few days to post. The agitatior is small & dumpy, quite wide though, it also has a screw nut on top, the only other one i thought which may fit would be one out of a 1101 servis twin, the 90's retro twin tub, as this was similar in size and also had a retention nut on top.
With regards to the control knob on top, this controlled a valve, there was one of two options, spin return or empty wash tub..hence why the earlier models had a cut-out in the wash lid so the hose could be kept in place while you were spinning and washing, and didn't have to remove the wash lid.
The Burco 21 ran for about 8-9 years, not sure if it made it too 1970. The Burco 40, was a cheaper version, and had an impeller, very similar to a Rolls.
Paul & Al, Burco did launch a machine called the Laundriair, it was basically a Parnall Spinwasher Mk1, with slightly different controls, but did exactly the same.
Looking forward to the finished result on the Burco.
Regards...Keith
