There's one almost exactly like it for sale on the Feebay right now, same color and everything, 19 hrs. left right ... "now" In would post the link "but" ....
I also use an Anker Art, said battery would last for 5 years I've had it almost 7 and still going strong, after recharging of course.

Some of the smaller ones definitely look Imperial, all foreign IMO, might all be Imperial as suspected ?? There are 4 or 5 in the second group I have no idea on from just the one shot ??
Duh sorry bout that, I was still stuck on the 1 in thing, my bad, guess it's time for me to sack out early Glad there's someone here to keep me on my toes tonight
