I wasn't able to find a thread that dealt with the company logos of less well know traditional hot rod part and service suppliers, but that may say more about my search skills than anything else. While certain logos have become iconic, and thus very familiar, e.g. the cigar chomping woodpecker of Clay Smith Cam fame, others were less well known. To get this thread started I'll post up a pic from a company that was a SoCal competitor of the much better know B&M Hydro company. D&F Hydro made very similar modifications to the venerable GM 4 speed hydramatic transmission of the late '40s, early '50s. The decal in the picture was their logo from the '60s, this one in the quarter window from my old H/G coupe back when that ran a D&F trans behind a GMC 302. I'd love to see other examples of lesser known companies/products, but then, maybe this should be open to any logos, well known or not.................your call.
