I went to Llangollen show in 1978 back then there where lots of russell types a few show type borders,and all other coloured terriers where classed as border lakeland red,grizzle,choc,black,black and tan and wheaton, a lot carried a lot of white on them from the russells in there make up,with in to years and write up in the working terrier year book and the working terrier by plummer the blacks became Patterdales. I was saw a old add posted somewhere on the Internet of frank bucks and he was selling his stuff as border / lakeland
