Fiamme
sprint rims
Dale
Phelps (Montagna lunga Colorado USA)1950's - the rims had "Brevetto Longhi" stamped above the "FIAMME ITALY" and a ferruled valve hole
Early to mid-60's - had "Brevetto Longhi" stamped above the "FIAMME ITALY" but no ferrule.
Mid 60's to early/mid-70's - had just the FIAMME ITALY stamping, Still no ferrule and still had the football-shaped transfer.
Mid-70's the transfers became rectangular with "FIAMME" lettering.
Image above right is of the adhesive decal found on the rims opposite the valve hole.

Fiamme sprint rim sections. Top - 'road' with braking surface
Bottom - lighter V 'track' section without braking surface
While researching Fiamme rims I realised I have such a rim with different markings fitted to a Solite track hub, possibly pre-1940, it is inscribed:-
BREVETTO LONGHI SA FIAMME MILANO
It has a ferrule at the valve hole. The marking is just to the right of the join which is the usual neatly rivetted Fiamme job although the rivets are visible on the hub side of the rim.
