[COLOR="DarkRed"]Hi WW....
The lugs are English as well, and the badge matches, so = same company. It's definitely a British drum.
Stickers...."goo-gone", "oops", or acetone are three liquids which remove glue residue...I suggest them in that order (not all three, though. Just whatever's available...goo-gone and opps being the better two products) But you gotta be gentle...that's chrome plating and it scratches so you cannot use anything abrasive to peel the glue off.
As far as value....it's just a chrome shell. It may be plated over brass..or plated over steel. se a magnet, see if it sticks. If it does, it's steel...if it doesn't, it's brass.
Brass is the preferable material...it's worth a bit more.
But it's a metal marching shell...so even all cleaned up and polished...with original hardware in functioning order.....worth maybe $75 on the used market. Unfortunate aspect is the dinged shell.
You could try, using a towel and rubber mallet, to undent the shell...or you could have an auto body shop try it if you REALLY wanted to get it cherry. The "home" version of the repair can be a bit risky, though...although I have done it on smaller shells a few times with decent results.[/COLOR]
