HI Barry...I remember those from the 1970's........when you bought a tin of Webley pellets, (500 size)....there was a "token" which was a printed disc of brown inhibitor paper....you sent off three I think, and got one of these in the post........have a look at troubleshooter's signature, he has a link to all things Webley, and has the nicest collection of accessories and factory do-dads out there, I am sure he has badges as well
found it!http://mynetimages.com/album/Trouble...Signs_-_Labels

(I have found the c55 labelled yellow oblong one in the 500 size of 1950's/60's green oblong tins from time to time
P.S........Would be nice if pellet manufacturers brought this system back as a little thank you........ for the amount bleedin lead costs these days
P.P.S.......reading the label, it was four tokens AND 20p...must be getting old, or wearing my rosy specs!
