I also visited the GCR yesterday and this Aveling caught my eye – it has some unusual features compared to later machines. Below are three photos of it. Having recently drilled and tapped 16 holes to secure the cylinder on to the boiler barrel of my 3” Foden, I had to take a photo of the cylinder on this engine – I think it has 8 bolts holding the cylinder down. Can anyone enlighten me as to what is going on with the cylinder end cover – it seems to allow access to the end of the steam chest/valve...? What material would the boiler be made from – wrought iron or steel?

The cylinder bolts are to hold the casting in position - it is not a steam tight joint. There will be two pipes from the boiler providing the steam supply with nuts and joints accessed originally via the manhole in the front tubeplate - the standard arrangement for Aveling rollers and engines up to the turn of the century. The boiler would originally have been WI - whether it is now depends on whether it has been reboilered which it appears to have been given the manhole in the barrel. The cylinder cover is combined as two parts with a front cover to the valve chest - again standard for rollers and engines of that age.

I would guess by the position of the man hole it was reboilered by Avelings Mine is number 2760 from 1890 and has the same features including being reboilered in 1912 Mike Typing at the same time as Paul |
The cylinder could be fed with steam by a nipple through the barrell shell so the base of the cylinder itself dos'nt need to be a steam tight joint. Though I.m not really up on Avelings , someone will correct me if i'm wrong. It could also be an elbow into the rear of the cyl, with the same effect. The boiler may well be steel.
