They were completely useless. :)The design of the R-10 interior boasted a nice streamlined ceiling which unfortunately gave us small fans that were noisier and less efficient than the older 'paddle' fans. If the R-10 and also the R-12/12 had a clerestory style roof then a different fan style would have been used. But in 1950 with the debut of the R-15, the problem of not using an exposed ceiling fan and smaller mini fans was solved with the axiflow style fan. This would used in car contracts for the next 17 years ending in the non airconditioned R-40 slants. Ah yes...the roaring axiflows. Bill Newkirk |
