Hi.
Trying to restore one of these and hit a snag...

In order to get the upper half of the case off, you need to remove the knobs - obviously.
But then you find out how they have been attached.
Grubscrew? D clip? Collect? No. no and no.
I've never seen this arrangement before, anyone else?

The dowel / split pin is steel and it isn't shifting.
I'm nervous about getting agricultural with it and applying to much percussive maintenenace..... One might be forgiven thinking AVO didn't want you to take the cover off...

Any ideas?
