No.... because I cannot clarify the vacuum pump on this loco (or the 1361 class) for myself. I shall try to explain in a day or so.

Chris, Graham,
thanks both.
The “pot” on the most recent photos is in the same place as the curiously shaped pot on Dave’s earlier post, but is a different shape. I’m going to have a look through my books and see if I can find out more. Might get a chance tomorrow evening.

Simon,
This link... GWR locomotive lubrication in the 1930's | Model Engineering Clearing House ... includes a decent photo of a pepper pot, also known as a vacuum relief valve; there is going to be one of those in the vacuum system somewhere. Until I started looking for the pepper pot on a 1366 class I believed that the valve was screwed into the top of the vacuum pump.... I cannot see it in any photos of either 1361 or 1366 class locos.

Hi Simon,
Just had a quick look on Google and came across the attached, which, towards the bottom, has a sectioned drawing of a GW vacuum pump. One of the three pots on top is a vacuum relief valve.
cheers
