That's a neat little tag - I must look in my tank bag to see if I got one too. Never opened it.
I found a tank over here recently in full working order and used at re-enactments. There were two problems though. Firstly, the chap couldn't positively confirm that it was made by M-H and not Cadillac - in fact he doesn't know how to tell who made them and this is a nut that I haven't yet cracked. It would be folly to purchase a non M-H tank even though they are precisely the same as the Cadillac made ones. I wouldn't want a Cadillac sitting in my M-H collection. Over here we call them "caddys" which can also mean a small box for keeping your loose tea leaves in!
The second problem was price. £220,000 = about 341,000 dollars. But it is a very nice one, one of only four in the UK and I have my tank consortium members thinking about it. We live in hope. It would be a pity to miss it and it was ono (or near offer) so could maybe get it down a bit. They say it would be a help if a decent quantity of ammunition came with a deal as quite a few of them have issues with politicians and local officials!!
Thanks also for your congratulations the other day on reaching 200 contributions - we try to do our best but I see that M-H in the east has now jumped into the lead! He must have nothing to do in this bitter cold spell we are experiencing!
