Hi all, new member here so hope this is allowed.
"Allowed" ... Hah! Not only allowed, but sincerely welcomed. That's a fantastic and fascinating tool. Thanks also for posting the thread about your collection. I'm really amazed at all the tools you've found.
Maybe you could also post something about "car boot sales." Are these organized events? How large are they, and how often are they held? Or are they just random things that pop up individually, or maybe advertised in the papers?
We do have "flea markets" here in the States, generally organized at public places, often by specific clubs like Ham radio operators or steam enthusiasts. Frequently, they're part of a larger exhibition the club is hosting. We also have Craigslist websites for most cities and towns, where people who have individual items for sale will advertise them. Craigs seems to have largely taken the place of newspaper classified ads. And then, of course, we have "garage sales" or "yard sales" at peoples' houses, several every weekend in smaller towns, large numbers in cities. Finally, there are charity shops (called "thrift stores" here). Several organizations have them. The largest chain is Goodwill Industries, which is nationwide.
I'm sure many of us here in the US would also appreciate hearing from other countries.
I have the paper work for that set and will scan it later and post it here for you. A word of extreme caution, do not try to adjust that barrel or take it apart till you have the paperwork. It is extremely fragile inside.
As always, thanks! Just for curiosity, have you been in touch with the Powerhouse Museum? I noticed their description included a note that "the object record is currently incomplete." They might enjoy a copy of the paperwork you have.
