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 is known as a nipple cylinder as there are two large pipe nipples into the boiler barrel that seal the steam joint. The front of the valve chest area does come off I wonder if it was an aid to machining to face the valve on a slotter type machine.
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
