Prewar single or twin? There are 7 in total counting
both years and all models. 1940 Wizard production totals are about 2500. 1941 figures probably more,but,
still a modest number.. Early 1942 production numbers murky if any were made as Wizards. Total number of prewar Kiekhaefer made Wizards is likely in 5 to 10 thousand range...subtract those that have not survived and those whose original decals are faded,worn or missing...there are more than a few prewar Kiekhaefer Wizards, Sea Kings and Mercurys about but very few that I have seen have original decals in anything like original condition.
Vinyl reproductions are available...so far as I know
original type decals not being made.
If someone having a prewar Wizard in like new condition is willing to share you may be lucky...maybe someone has a set of unused
prewar replacement decals...to copy.
