For sure, yours was one that ended up in the hands of one who appreciated it. Stellar build, yours is a one-of-a-kind.
What in Frankenstein's laboratory is going on with your particular Shimergo rendering? How many cogs on that cassette? Eight maybe? Maybe it's a freewheel?
Glad to know that such tire sizes will fit! Are those the narrowest 650b tires available by chance? I see it is pictured still with 700c.
BTW, I remember that SR used the Gran Course moniker around 1979, for a ~27-pound road bike pretty far down in their lineup.
