Low end ? Crescent / Need some info
 

Working on moving forward on some “rescued/project bikes” that have been languishing in the back corner of my shop for more than a few years. As of yesterday, became interested in a Crescent-brand bike that I’m guessing is from the ‘60s maybe ‘70s. I did do a bit of Google research and learned a few general things but would like a few more specifics. I can’t remember exactly how or even when I came to have this bike but certainly within the last 15 years. I’m not even sure that it was complete but pretty sure that I stripped more than a few components from it that went into my “parts boxes”.
Here are a few pics of the stripped down frame and fork:

There’s no indication of the “Model” and I’m unable to find a serial number anywhere on the frame. There is a decal on the back side of the seat tube stating “Made in Brazil”. Otherwise the head tube badge and other decals seem to be the same as those on Crescent-brand bikes viewed in my Google search. As can be seen in the pics, it has a lugged frame and the derailer hanger is part of the right rear dropout.

The one piece “Monark” chromed steel crank, threaded for 1/2” pedals, pretty much puts it at the low end of the Crescent product line (IMHO). The steel chainrings (46t & 52t) are bolted to a triangular spider. The chrome “pant protector” also places this beast near the low end.
The fork is chrome “tipped” on the lower half but as in many forks like this, are completely chromed (as seen by the chrome steerer tube).

What I’d like to know about this bike is the approximate model year and name and perhaps more importantly, the components that were likely to have come on it. If I still have the parts in the “parts boxes”, I’ll restore them to the bike!
Any info will be appreciated.

Rear mech hanger looks welded on to a stamped dropout - is the paint original there?

thanks very much for sharing this machine with the forum. ;)

at first glance was puzzled by the model as it exhibits the same taper tubes and plate style chainstay bridge as do the low end lugless models yet it is lugged.

here is a Sweden manufactured lugless model 305 from the early 1970's for example -

then as got down into the message found the statement of the "made in Brasil" transfer.

MCB maintained an operation in Brasil for a time; do not know if it were theirs directly or if a licensee.

here is one other example from that nation which turned up several years back -

the SKANIA transfer in evidence here is a third marque belonging to MCB

appears to date from the early 1970's

the forum has several members located in Sweden who are very knowledgeable as to MCB products

they shall be able to give you much more & better information

yes, that is how it appears on me scren as well

the dropouts look to be Agrati item Nr. 000.8002

the fork ends are a match being Agrati N. 000.8010

gear hanger appears not only to be added but cut from thicker stock than dropout

this may have been done at the plant in Brasil; doubt it to be a post-manufacture alteration

Brasilian produced Crescent machines exhibit a mix of European, Japanese and indigenous Brasilian bits

On closer inspection, the derailer hanger DOES appear to be welded on to the dropout :rolleyes:. I guess I didn’t even think that it would be that way. The paint looks original but I can’t really say for sure :foo:.

The hanger IS thicker than the dropout! The hub side appears seamless and the hanger side has a reasonably nice “filet” style bead. I’m thinking done at the factory but again, can’t say for sure.

I’m not actually sure what the “fate” of this bike will be :foo:. Much will depend on information hopefully coming from members in Sweden :thumb:.
