... I have a Air-King from 64 where the original price is written on the box as GBP 54.-
Now a nice play around with 1964 vs. 2010 figures:
Compared to the retail price index this will be equivalent to GBP 853.-
Compared to the share of GDP it will be equivalent to GBP 2360.-
(according to
http://www.measuringworth.com/ukcompare/result.php)
Anyway, it was a good investment compared to the pricing of the current model and when worn it would defend the money against inflation as the price for used Air-Kings are around the inflation corrected value. All this given that the collectors don't care about Air-Kings

Bye,
