RING SET+.040 5T 46- NOS
Piston ring set, .040 oversize, for the 5T, listed as NOS stock under this number or its alias B209.
This is a piston ring set for the 5T model, in the .040 oversize, listed in the older catalogs as NOS stock. The 5T designation and the .040 over spec are what you match against the bore your cylinder has been taken out to on a rebuild — if the barrel has already been bored oversize, this is the size you order to go with it.

The manufacturer tag on file says Amal, but ring sets aren't something Amal made — Amal built carburetors. This is a piston ring set, not a carb part, and we wouldn't put an Amal name on it with any confidence. The alias B209 is the other number this same set has shown up under in the records, so if your parts book or an old invoice has B209 written on it, that's this same item.
We don't have much more detail on this one beyond what's above. Ring sets are matched close to actual bore diameter, so if you're not certain your engine has been bored to .040 over, give us a call before ordering and we'll sort out the fitment with you.
