Can anyone help me identify what this loco is? I bought it as a part-made kit on ebay and want to finish it as correctly as I can.

I thought it was a Holden B12, but someone here probably knows better...





Thanks for any ideas! 

What do you think:

[smg id=13176]

A Class S69 

Also the B12 and S69 were sometimes listed as Holden B12 (Ger class S69)
The only external difference between the B12 & the S69 I can see is that the
S69 has a taller funnel and higher pressure dome.

B12

Hmmm.... could well be!! 

Thats a BH Enterprises whitemetal GER B12 kit on a Poole Farish chassis (probably a Prairie or Hall with the connecting rod assembly and cylinders removed).

Cheers,

Oldun's top photo labelled 'S69' is actually a B12/4. These locos were rebuilt from the original GER S69/LNER B12 by use of a round top, instead of Belpaire, boiler of the same diameter as the original boilers. They retained the original GER smokebox, chimney, and I think , original snifter valves. They were based in Scotland on the old GNSR section. When withdrawn from 1948 onward, the boilers were re-used to reboiler the ex GER J20s from Belpaire to round top firebox.
The lower picture is a B12/3 rebuild, which used a larger diameter smokebox and boiler. These remained generally shedded on the GER section, though there were odd ones away from this system (eg M&GN, but others wandered a little). They could be seen though, I think, at Oxford on workings from Cambridge.
The kit appears to be the BH Enterprises B12/3; easiest way to distinguish is the smokebox bottom, which was flat on the B12/3 but remained round on the B12/4.
