We visited Bressingham Estate and steam museum recently, and found this locomotive displayed in the parking lot. It is obviously not in running order but there is evidence of some preservation work being done on it. These was no-one to ask and there is no info on their website. The guage, while I did not measure it, looks like standard 4' 8 1/2".
There is a small plate attached to the boiler in the cab, which appears to say "TAMZELLA 1948". You can try and decipher the rest. Could the steam buffs offer any informed guesses as to it's origin?
