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?
