Hello
HepsibarWell,
Webb has a long heritage and I have been
trying to understand the AUS perspective for some years.
The
Wasp was the six-bladed 12" model.
It formed a part of the holy Webb
trinity:
the
Whippet,
Wasp, and
Witch.
I would rate the
Whippet good;
Wasp better; and
Witch great
[Apologies to Devo fans].
My best guess is that the
Wasp was a post-war model
introduced here in about
1947.
I would date AUS sold machines from that time to about the mid-1950s
[based on newsprint advertisements]
It sold over many decades: -

Hope this helps.----------------------------------
