WTD: Austrian 30.8/26mm threaded headset

Long shot!
Anyone have a complete (or at least lock nut and top race) Austrian 1” headset? These are the rare old shit found on base level vintage Puch - maybe also compatible with some Russian frames but not sure.

What's different about the? Cup od? Thread pitch?

If it's just the thread pitch is it like a Raleigh Twenty where it's close enough that you can run a 'normal' tap down it and it'll sort of push the metal around to make it fit?

All of the things

I am in austria until tomorrow lunchtime. I noticed there is a secondhand bike shop near my hotel. If i get time in the morning i will ask them if they have such a thing. I am in Graz, the home of Puch!

That is very kind! Thank you

Oooof this is good, dying to know if @wynne succeeds... feels like old style forum stuff this

Well, i tried, but i failed.
Both local bike shops were still closed at midday and i had to catch a train. It's annoying because both had lights on and people inside when i called, but no one was answering the door. But, if you get stuck you could contact these one of these places:

Both look to have LOTS of old bits of bike.

Sorry to have raised hopes.

No worries! Thanks for trying!

Found one in an Austrian shop online! NOS OTP WOW
Luckily got a reasonable 25.4 seat post to go with it. Wild. Now have no excuses (apart from cash) to build up a monstrosity
