Tim:

Possibly you have seen the thread entitled "Konig vs. Flathead" in the Outboard History section of BRF. The final two years both mfgrs were competing against each other with new motors available before Waldman's death, and the results of National and World Championship races in the US, will be posted within the next 24 hrs, if you are interested. I have been very busy with some other things since the last posts on this subject, but will get the final results up shortly.

Perhaps this will help you more completely in your endeavour.
