I'll be sending you some emails later tonight - hope your inbox doesn't send them all to 'spam'... LOL
Appearance-wise these Westys are almost identical to the CLB-6 and CD-6. Mine were indeed built in Canada at the old Westinghouse plant in Hamilton (not far from Toronto), Ontario!
There are some slight cosmetic differences - the front panel on the Canadian models is completely smooth while the American models have a slight square inset where the control dials are. The Canadian division probably chose to not re-tool their assembly line...
Otherwise, the components and parts are the same.
Did you find these locally or did this involve a major road trip??
