And another "Cloggy",
Welcome to Retrobike
Watch out, it's a slippery slope from here on, and by the looks of your splendid duo you don't stand a chance

Great looking Proflex, really well detailed, and though I like S-Bikes in general, it's not as "finished" as the 957 imho.
Who's your LBS, Stappenbelt maybe? I remember rummiging around his back rooms and attic long time ago, it was a veritable treasure cove bitd.
Enjoy!!
