I have a 1933 Perfect Circle ring catalog that lists, in the Truck/Bus section, Hannah model 2Ewith a Wauk 6MK, and Model 5E with a Wauk 6SRK, both with 1931 date...

I  probably have 20 or so other catalogs that cover this period, "HANNAH" is not listed in any others or in thelater period catalogsI have, asmittedly wek on Const  Eqpmt.....

I have Mroz's US Tks and Comm'l Cars (no listing) and Auto Qtly's 5000 Marques, covering cars, trks and rumored models (mo listing) and Std Cat US Cars (no listing), nor fo I find anything close enough to've been a typo...Google also fails me...

So: any ideas?? That catalog includes Haiss  Loaders, so it might be something like that...

Dying of curiosity; many thxx for any suggestions...
