Konica III opening, pointers?

[Captain Bedworthy]

Hello Gentlemen. I was recently given a Konica III and was wowed by it. I also see a blade that's either broken or just jumped the track. I have some skill, but haven't opened one of these. Any pointers on how to approach the aperture race? I've read the pointers about Seikosha MXL shutters and where to find blades if it's a snapped pinion. I've re-laid the blades in various Compurs so imagine I'll be okay, but this example is near mint and I want it to stay that way. Thanks!

Not really sure what to say apart from unscrew the assembly from the back. It's pretty easy to get to in this camera.

Are you referring to an aperture blade or shutter blade?

Aperture. The shutter's really spot on even at the slower speeds, which is why I'm keen to repair it. Not having it out right now can't recall if the shutter is before (in front of) or after (behind) the aperture. But if it's in from the back I hope it's the latter. Thanks.
