Aveling feed pump

[johnwm]

I am in the (sloooow) process of rebuilding an Aveling (9212) from a mixed collection of bits. You can laugh at my efforts on our website www.essexsteam.co.uk

The boiler is now close to reassembly and the pump needs reassembling. It is a R10 pump (2 chambers) and I need some drawings/sketches/photos or whatever as the internals are all missing. I am now stuck as I can't refit the front tubeplate without fitting the pump, as I would like to fit the carrot bolts and pump while I can still access the inside of the barrel.

If anyone can help with any info I will be very grateful
