Hi Heinz,
yes, it's nice to have a few personal items from pilot/aircrew.
The first time I met Judy was at Wangaratta air show I think I sold her an ASI and some other items.
I sold her a few things just before I came to Norway to get married.
I've done a bit of flight training at Moorabbin. I sat in the Beaufighter at the museum once and donated a WW2 USAAF leather jacket to the museum (it was pretty rough but if folded right it would look nice in a cockpit).
cheers,
-John
