Help Identifying Movement

[Trav2004]

Hello I was wondering if anyone had advice as to how to identify this Heloisa movement that I have. The balance spring is broken and I would like to replace it if I can find the correct type. I looked under the balance and other various bridges and I couldnt find any markings. I did find an 85 on the front under the dial (see photo).  The closest I could find in the bestfit catalog from the 60's is an A Schild 547 but it didn't seem like an exact fit.

Hi, the setting bridge looks similiar to a 7 3/4 Felsa 171, 8 3/4 Felsa 87r but the clutch lever does not, the closest I can find is the A. Schild 8 3/4 547, it shows two setting bridges and the correct shaped clutch lever, good luck with this project .....

I thought it looked similar to the 547 also but I could find next to nothing in parts for it to compare it to in pictures
