Does anyone have a user manual for this?

Before everyone says "it's a Eumig", it is not exactly the same as any specific Eumig model. It's probably closest to the Eumig 820, since I believe the Bolex also has High Quality Sound, but it doesn't have the programmable recording features. It does have a film counter, though.

I'm interested mostly in the low-level specs. Yes, I know I can look at the Super 8 database, but that is not always 100% accurate for the low-level electronic details.

Thanks
