It's an S.C.

They had fender eyelets in the early 60's (like most Italian racing bikes).

Update!

Still working away slowly, things are coming together very nicely. I'm amazed to find many of these parts are in such great condition as I break them down.

My most recent big project was the front wheel. It has been completely disassembled and rebuilt with a new (to me) rim, the same Fiamme Red Label that came stock on the bike. Scraped the old glue off with a screwdriver, steel wool, WD-40, and lots of patience. Spokes were cleaned individually with steel wool; nipples were individually cleaned with a Dremel and brass brush. Mother's polished up the hub and rims very nicely.

The hub has no damage, just a very narrow ring of wear around the cones but that is it. Repacked with new bearings and Phil Wood grease, it feels amazing and spins forever.

I would never recommend building a wheel with used nipples and spokes - that is, unless it's something like this :). It actually came together very nicely. Still needs final tensioning, but otherwise done. I'm estimating about 10 cumulative hours for the whole project. Enjoy the pics.

Your wheels look amazing. They really cleaned up well. Are they original to the bike? The reason I ask is because I was told that Fiammes like yours, which lack text above the helmet, are late 60's to around 1970. Yours are identical to what I used to restore my ca. '70 Masi. Masi Bob (Hovey) told me that early to mid-60's Fiammes say Brev. Longhi or something like that above the helmet. I'm more curious than anything else. It's so hard, at least for me, to pin down when Fiammes were in production.

Everything is original except for the rims. The logo on the original rims were unidentifiable as far as the Fiamme logo goes, the front had no label and the rear was chipped to the point that you could only tell it was the oval red label logo. I went with these after months of looking on ebay and craigslist with no luck of finding anything usable for a restoration, and then found these from a local vintage shop.

I saw the wheels today. The pictures don't do them justice.

Wow! That is excellent work!

I think you made a great choice. I wouldn't lose any sleep over the label. I don't know if what I was told is correct; even if it is, it's such an esoteric detail that it's probably not worth worrying about. Your rims are beautiful and of the period. Enjoy them. They look wonderful with those polished high flange hubs.
