Help Frameset identification

[Guidelazeri]

Hi, it's my first post here.
This bike is on a sales website in Brazil, it's not mine but it's my size. The frame was repainted and assembled with different components.
Do you have any idea what the manufacturer/model of this set could be?
Thanks in advance.

Afraid to say the photos are not ringing any bells for me. Nice lugs and drop outs though, so definitely a quality frame. Could be Brazilian?

The owner of the bike didn't find any inscription engraved on the frame, possibly it was covered by the paint. I don't think it is Brazilian.

The owner said it has 10,7 kg in weight total.

Doesn't really help with identification. Without a headbadge, decals or serial numbers, it's almost impossible to say what it is, or isn't.

It is very unusual.

Yep, should be the smoking gun that gives up the framebuilder.

Welcome, @Guidelazeri !

I don't know who made that frame, but I like it. I looks well made, and very sturdy. Almost as if the builder was more into mountain or touring bikes than racing machines.

Perhaps @juvela has some insights on the origin of the frame parts that were used?
