The exact name of this saw is not found anywhere on the case, but it's certainly a "Herkules HMB" series machine and we're going with model "4000" as the manual we could find comes extremely close at least. A generic name for this machine which is sold by different companies without apparent differences is "4x6 bandsaw".
This tool is not ready for use yet since not all commissioning steps have been completed. The process is also tracked on GitHub. Feel free to contribute to making it usable, any help is very welcome!

Upgrades
There is an interesting video series about improving this rather generic machine to a much higher standard.
Let's sum up the main ideas and our progress here:
- replace the standard blade with a bimetal one
- according to the author, 14 tpi is already a bit too fine for many purposes as too many teeth are in the cut at once, but we'll need to see what kinds of tooth ratios are available
- replace certain screws with star knobs/knurled bolts for tool-free tightening?
- replace belt with a better fitting one? apparently, the originals are too thin
- check oil coverage in the gear box? (not shown, but apparently recommended by other online sources - as our machine is a bit old, we should keep this in mind)
- square the table and/or fences?
- after some fiddling with the blade, we got pretty good results with aluminum in initial tests, but we should check the cast quality. Perhaps harder materials will show us we're still a bit off
- change spring bracket for lower balance position?
- add 90° stop (along with removing play from the fixed fence screw
- add sliding tray to collect chips (in the video, he just used a simple plastic box lid)
- table for vertical use??
- if included with our saw, we should probably remove this and keep the two machine types separate!
