Dave,
I completed the survey, definately a loco I'd like to see produced.
Sorry if someone else has already mentioned this, is it worth approaching the Class G5 Locomotive Company and doing a similiar survey for the Class G5 0-4-4T? Excuse my ignorance but has the O2 tank your currently producing for Kernow got a similiar chassis? Putting you in a good position to commission one of these as well. It would be another nice looking tank engine, highly sought after and start filling the NER gaps.
Just a thought.
Regards Paul.
