Norton 850 Roadster Acc. Cover, Fireflake Royal Blue, double line trim
Fireflake Royal Blue side cover with double line trim for the 850 Roadster, PN 063503/042.
This is a side cover, sometimes called an accessory cover, finished in Fireflake Royal Blue with the double line trim treatment. The catalog entry ties it to the 850 Roadster and places it in the Side Covers, Accessory Covers group. It's a cosmetic panel, not a mechanical part - it covers the frame area under the seat where the battery and electrics live on many British twins and triples of this era.

The canonical part number is 063503/042, and our record only shows it appearing once, for the 1973 model year, so this looks like a specific color-and-trim variant rather than a generic cover casting. If you're trying to match paint and trim on a Norton Commando 850 Roadster, the Fireflake Royal Blue with double line trim is the detail to confirm against your existing tinware before you order.
Given how thin our documentation is on this one, it's worth calling the shop to confirm fitment and finish match before you commit to a purchase.
