“Northwest trolley rail fan group” & “Trolleyland?

Greetings folks,

Does any long time Seattle residents, or maybe rail buffs know of a “north west trolley rail fan group” or a defunct railroad museum named “Trolleyland”?

They were active around the years of 1958-1975, to my knowledge they purchased 3 Vancouver BC trams with the goal to run them in a museum named Trolleyland in grand mound.
