Hi all, I've been at a few auctions recently and this was included in one of the lots which I was successful in winning. I have done a bit of digging with regards to finding out more about this item, but so far I've not found anything other than a couple of photos on google which don't lead anywhere unfortunately. Can anyone here shed any light on this, and when it was used and who used it, and without coming across as a bit cheeky a rough value? As I am planning on selling it on as it's not really in my area of interest.
