I bought my Empire Professional in Spring 1976 from the Happy Outdoorsman sporting goods store on Pembina Highway in Winnipeg. Pretty decent specs for the price... double butted High Tensile tubes
, alloy everything, Shimano Titlist derailleurs, and Shimano 600 brake levers and sidepull calipers.
I let it go 2 years later when I outgrew the seatpost. More recently I acquired an exact duplicate, except 1 framesize larger, and restored it (since the paint was pretty far gone in many areas). Now the replacement is in the same use as the original, i.e. regular workout rides around the district.
