chanced upon this machine discussed over at the Tonton forum in course of a search

it begins as an unknown
one poster uploaded an image of a Hirondelle (a marque belonging to Manufrance)
this was done simply as an example of the frame style and not an ID suggestion

it appears to have been constructed with the same lug pattern as our subject cycle and came with a Torevess headset

the vertical spacing for its head emblem fastener holes even looks to be about the same, at least by eye, as that for the frame under discussion

one kicker: the owner reports it came to him with a stem marked Tigra

head -




steerer markings -





unfortunately, taper tube ends are not pointed -




even came with a Torvess cottered bottom bracket assembly -




Tigra marked stem -




example looks to date from the early to mid 1950's
