Never mind Chris - some people insist that all GWR locos look the same... :)):))

They do, it's just the names and numbers that enable you to identify them. :p

Must admit though that my knowledge of early LSWR types isn't what it should be. I am of course suitably educated on Beattie Well Tanks and the variaties of T9 but my period of interest is mid 50s onwards so I've not really spent much time looking at the earlier types that disappeared before this.

Hi - I am currently trying to work out how to fit inside valve gear to a 7mm Beattie Well Tank, I understand it was Allan valve gear, but I have no idea of the actual layout - do you have any diagrams, photos etc that I could borrow please? Thanks

Are you sure that's correct? Not really my area - more @Steph Dale's but I'd always thought they were Stephenson's. The 1366 panniers and the 1361s certainly do have Allan gear (supposedly because the Cornwall Minerals Railway locos they're derived from did), but they're obviously nothing to do with the Beattie design...

Hello

This might be the digital equivalent of throwing bolognaise at the wall (additional mess, and not advancing the subject at hand one jot), but Laurie Griffin's site has Allan motion:

12-017: General Outside cylinder working Allan straight link inside motion for LSWR Beattie & HR locomotives & others – LG Miniatures

Cheers

Perhaps more useful than anything I could say on the topic - does this help at all?

2-4-0T - Beattie Well Tank, 5ft 6ins Driving Wheels (GA of the thing as built).

This barely technically-literate rude mechanical has no idea what type of valve gear it shows, however - though it does demonstrate what is there which is - hopefully - a help.
The drawing I believe shows Allan gear. The straight expansion link of the motion can be made out on the drawing.

Which although reversed matches the diagram from this link.

What a cornucopia of helpful advice... Thanks folks... I had assumed it was Allan's, because (a) Griffin's website said Beattie locos and (b) there is precious little room to get valve gear in, so the reduced height of Allan gear would make sense...
In fact why am I doing it anyway? Just because it is a challenge..! Fact is, with this corona-virus scare (even though here in Hong Kong we have far fewer cases than plenty of other countries), self and wife are tending to hunker down at home and not go out much, so I am catching up on the pile of kits on the shelf, and had a fit of masochism to attempt inside gear on the Beattie...
Well done, team - much appreciated!
Thanks again
