I think this has been noted, but at least late 80's to 90's silver was not that common. my '89 Miyata 1400 came with Wolber rims, dark gray, v-section.
of course the look you want is the look you want, so make sure and post when you are done
P.S
I know you said you did not want to go Tubular, but you have a bunch of tubular rims available, the ride for fast road bikes is really good on tubulars, and if you go the Tufo system tubular is not that big of a pain, tape not adhesive, durable tires, with sealant, so it might be worth taking another look at
If you order from a uk bike shop prices are really reasonable. ( $83 for 3 S33 24mm tires, 3 tape) or ( $142 for 2 higher end tires and 1 s33 as backup and 3 tapes)
