More of the same.

Looks like the blue on blue idea (bad as it is) is a little cleaned up. Color of the distributor is improved, but a rectifier jumped on the latest spy pictures. Text says this will be removed for the finished motor. 75H's used "total loss" ignition/charging (just a pair of dry cell batteries). Total loss just means a regular battery ignition with no charging circuit; you can ony run until the batteries die. Fortunately, regular heat racing and speed record attempts were well in the range of one set of batteries.
Another complaint I have: the carbs are modeled after the MK75/Merc 600 AJ series carb, not the KA3A/KA6A's that are accurate for the 75H.
I tried to lend them a prop much like the one Entrop used to set the speed record, but I think they used a regular Merc800 Speedmaster prop.
