Thanks for all the information Tinplate Art...the forum is one of the few places that folks like me can increase their knowledge of the model / toy train hobby. lewrail the picture of the Walkers & Holtzhaphel 0-6-0 was really interesting and again lists a manufacturer I had not heard of before...and to think the data came from another Dr. Blake fan !!
Thanks to all for posting - I will be back home in a week or so and hopefully will be able to post some of the tinplate that has arrived from e-bay over the last 2 months.
