ME Super tool to remove ASA dial nut

I want to remove the top cover from my ME Super, but the nut on the ASA dial is really stuck. I don't have a proper tool which I think is this in the service manual, attached.

I've tried using two flathead small screwdrivers but I can't get it to move, and I'm just damaging it.

Where can I get a tool like this, or how can I get it off?!

Try looking for a "Camera Spanner Wrench", such as the one pictured here: 5mm Spanner Wrench Tool | USCamera | Downloads Parts Tools MoreUSCamera

I have one I got off ebay similar to this: Adjustable Camera Lens Spanner Wrench 3 Tips Flat Opening Open Repair Tool set | eBay

These are adjustable and have changeable tips to cover many tasks.

Also, is that nut a left hand thread? I think the film advance lever nut is left hand, but I don't know about the ASA dial.

Good luck!

Does the manual say if it's a left or right hand turn?

I found a guide that said it was a "conventional thread", which I assume means right handed.

That camera wrench looks perfect. The cheaper ones seem to start at 10mm though, will do some digging and see if I can find one that goes smaller. The dial nut holes are around 8mm apart.

The cheaper ones may not be worth the money even if they did fit:

You could always take a screw driver and grind it down to have 8mm prongs. Don't forget the protective eyewear when grinding or using the makeshift tool.

This thing seems super stuck, so those cheaper wrench things may not work. A ground down screwdriver may work well, but then I need tools to grind down the screwdriver!

I managed to make my own tool by filing down a door key bought from a hardware.

I use a needle nose pliers that I ground down the tips. Most lens span wrenches don't get close enough for those collar nuts. Some old Starrett compass deviders also make a nice tool for this, but you need a shorter one (less flex in the arms) and you still need to bring the pointed tops to make them like a screwdriver tip.
