Thanks. Whatever it is , it is an interesting piece that I'm glad I've had the opportunity to show and engage in discussion. I think the engraving is period or at least really old and I saw some nice poo patina on it. Maybe a veteran who decided to make a fob out if it post WWI. Will never know, but what ever it is it makes for a great conversation....... maybe I will buy it...just for that reason...and if the price is right.
