I've initiated a survey in order to try to locate and identify all surviving machines. In issue 9, I listed twenty nine machines that I could definitely account for. Issue 10 (which will be in the post later this week) lists seventy seven, so the list has grown considerably. However, there are still many more out there, and of course only readers of the magazine have participated so far.
So if any users of this site own or know of a machine (or several) please let me know. It is important that owners anonymity is respected, so please do not post owner's names on this site. Email me any information you have (through this site) and I'll include all newly identified machines on the list. (obviously, I shall need to know owner's names, or at least where the machines are located in order that details are not duplicated).
At a later date, I shall post the full list in this thread. In the meantime, I can reveal that the most common surviver so far is 'The Night Watchman' with twelve accounted for at present.
Thanks (in anticipation) for your help.
Here's a splendid collection of Bolland working models at Chessington Zoo, sometime in the 1960s
