its a blast from the past mate,my grandad had 1 when i was a kid,it was a right tough little fecker,it was a awesome worker rats rabbit,did charlie for fun and lived to a ripe old age of 11,sadly tho i think theyve gone the same way as a lot of other working terrier breeds,either ruined by the crufts lot or sadly no longer exist,i hope you find some working strain out there cos if my grandads dog was owt go by they were very handy dogs
