Excellent! He's a nice, although very busy, chap. I'm sure he'll help if he can.

He helped me with my research.
Had some really nice photos.
Odd the tank on 299 is flat topped. I remember reading they were recessed as I built mine, probably to ease storing of extra coal, tools, etc. But perhaps one of the modifications the GER made.

For what it's worth, here is the one that I built in 5" some years ago.

It may be that the photos of 229 show pieces of wood placed on the tank, I guess to stop rain collecting and causing rust.

Doesnt look like wood to me. Though I do agree a change like that would be to prevent rust buildup.
Didnt the GER increase the coal space, negating the need to pile on the tank?
Looking at the drawings I worked off of, the Neilson built ones had a reccesed top, however the GER ones isnt noted on the drawing, which Id take as flush.

I’ve had a reply from Bill Parker at The Flour Mill, he tells me the tank had an extension fitted at Chepstow, so when he originally acquired 229, he removed the extension and fitted a flat top.
I have not seen any photos of the top of the tank on any of the original engines, and the JAGardner drawing could be read either way.
This drawing was compiled from some existing detail drawings, so maybe hidden away is the answer ?
The tank now is in very poor condition and a new one is on the cards as the restoration progresses.

That adds a nice bit of detail to the story of 229 - hopefully it helps your model too.

Just looked out Mr Gardner's drawing in Model Railways for August 1972. He gives a specific detail of the top edge of the tank with a 2 inch upstand as well as a half round bead of about 1 inch width. The drawings were prepared from Nielsen's works drawing no 8476 of 1874. Which goes to show, never trust a preserved machine to be in as built condition .

Thanks to unklian, the tank top issue ? was staring me in the face. The drawing by J A Gardner has a detail that reveals all.
I was focusing on the other, later engine, so missed this bit.
So, although it makes the tank approx 1.5mm too high, it was possible to include the detail.
I wanted some 1.5mm angle but had to resort to splitting some square brass tube and filing down either edge to size, and soldered the 4 pieces around the tank top.
So then I followed round with some "D" shaped beading to finish it off.
Cab next, should be a bit easier.

Who'll notice 1.5mm anyway?
Im shocked how clean you managed to get it all post soldering.

Im not THAT bad at soldering!
Ok Im pretty bad.

Spent a bit of time on the frames, having received some wheelsets. Cylinders attached to the frames with screws, and motion brackets soldered in place.
Next, internal tubing in the cylinder blocks to guide the piston rods, slidebars attached into cylinder rear and a very snug fit into the motion brackets - very accurate lasercutting artwork by Spitfire.
And I've polished the slidebars.
So did some "dry" assembly of crossheads and rods, the leading wheelset crankpins need replacing because of the usual problem of clearance between them and the back of the crossheads - the Slaters crankpins are very nice but I shall make some shorter versions.
Also looking at suitable motors, I have quite a collection of possibilities, but a nice double reduction gearbox for slow running will fit the bill.
Not decided yet about springing the axleboxes.

I think you'd notice the difference with springing (or rather, you notice a lack of springing, if you don't fit it) try comparing a sprung, and an unsprung wagon.
