This one is gonna take some of the masters to figure out.
except for the cottered crank, very similar to an early postwar Schwinn New World
here's a '46 Superior with a slightly different cottered crank
'46 Continental is close
basically, a Schwinn copy of a Raleigh Sports
I'm no expert but it sure looks like it was a Paramount Tourist, but no lugs. Notice the sliced off seat stays at the seat tube. Chain ring looks prewar and could be a late pre war Superior/World Racer converted. Fork and front hub are later issues.
39 pic of the crank set.
The more I look at that frame the idea that it could be a Schwinn disappears. Lots of Schwinn parts but not the frame.
Frame and chainset look a little French, and does that read "made in France" on the front hub?
What is the rear hub?
Looks like a bit of a mish-mash, but could make a nice rider.
curious, because it's sure fillet-brazed
Interesting chaingaurd mounts. Not standard mounts.
Hello jrodarod and thank you for sharing this curious riddle with the forum.
your initial message contained no text so am unsure if this bicycle is something you own or something you saw somewhere. since there is a handwritten price sticker on the saddle i am thinking it was seen a sale of some sort as there appear to be other machines in the background. mention this only because if it were yours we could ask for measurements. am guessing it is not so we are limited to the information contained in the images.
fine job with the size format and detail of all the photos.
much like dnc1 above i began noticing numerous French points straightaway.
beginning with the frame -
dropouts are NERVEX item nr. 1025
seat tube chainguard mount is NERVEX item nr. 879
down tube chaingurd mount is NERVEX item nr. 879bis
arched chainstay bridge is part of a NERVEX series called "curved bridges unflanged" which runs from nr. 600 to nr. 635, one would need to know the exact dimensions to identify it specifically.
vertically drilled arched brake bridge is also part of this same series.
braze-on pump peg is NERVEX item nr. 845
lugless bottom bracket shell is likely NERVEX item nr. 3300 but have no way to verify from photos.
crown - have not been able to locate maker for this. suspect it is either BOCAMA or NERVEX and was discontinued prior to the publication date of the reference materials i have at hand.
this is a Haubtmann product. despite the German sounding name Achille Haubtmann was a French citizen who located his cycle fittings manufacturing business in Saint-Etienne in 1909. It passed from him to his son and later on to his grandson. in later years Haubtmann products were known under the name SOLIDA. the chainset is of an unusual design wherein the chainwheel threads onto the crank arm. VB has a listing for a later example of this set made under the SOLIDA name:
in this old Haubtmann advert one can see on the left a chainwheel identical to the one on the bicycle. note how the artist has indicated the threads on the inner edge of the hole for the crank arm:
Schwinn marked brake calipers -
note how on the front caliper the pads are all the way at the top of the adjustment slot while on the rear they are all the way at the bottom. if frame and calipers had been designed to go together one would expect to see pads near the centre of the slot in bot cases. note also in the profile image of the front caliper how the spring has been mashed up directly against the fork crown. mounted by someone who did not employ the usual curved mounting washer.
Front hub is Atom brand from Maillard of France. do front and rear rims match?
struck by the apparent odd design of having serrations on the locknut. suspect what is going on there is that the locknut threads down inside the lock washer giving the appearance of a single piece.
suspect this may be a CENTRIX product but have no hard information. this French firm produced both steel and alloy stems and bars. Schwinn experts will be familiar with them for supplying the stems on the first year Continental model. the firm went out of business in 1962.
so am leaning toward thinking bicycle of French origin but have no ideas as to manufacturer.
fantastic observation and research, thanks for posting.
@juvela here you are. First time I have dropped in for a bit and one of the first threads I see has this detailed description. Amazing as always.
