Lorry Dunning has just had his second part of three published in Antique Power Magazine.
It is about the Best steamers, there are 13 known to exist with only 4 in operation. He has done a good job given a detailed history and picture of each one. I hope you get the chance to check it out.
We need to get him to have his articles in the ACMOC mag!

I was glad to read the Ken Eders is SN: 188 and is the second oldest that is in operation, the Heidrick machine SN: 175 is the oldest that is operational.
