Asking info about the Stump-jumper look a like

[SMiZ]

Dear all,
I just got a vintage bike that looks similar to the Stumpjumper old model. The info on its frame only Tange decal and a blurred yellow ring.
The bike has 47 cm. long tail and unicrown fork. Having searched the internet, I found the frame similar to early model of the Stumpjumper or Mongoose MTB. Please amy has seen or know the brand origin, I would very much appreciate for your sharing.
Thank you.

Afraid I can't help with a brand but she's a beauty. Good score

Man that's an odd one. Even the serial number screams stumpy or at least specialized. M6J - 1986 built in October likely, but if its an 1986 stumpy it should have a unicorn fork.

Another spesh model? From the same factory?

Cool ride. Let me know if you wanna part with that seat. I have a 1985 Team it would be awesome on

Nice bike nonetheless!

Re:

Seat cluster is wrong for a Specialized. I'm sure someone will get it. Looks lovely though

Re:

Tange decal can't be original?

Have you got more pictures of the headtube?

Lovely bike but take the kickstand off asap and sort the paint loss that will be underneath it. Ruins the look of a fantastic bike.
