Bonneville D tower?

[mathrich]

Does anyone know what kind of tower this is? (it is sitting under a D-Mod with a 44xs gearcase on the bottom) Based on the shape it looks like a Bonneville tower but I was under the impression those were only made for the 6 cylinder motors. Did Bob Florian make towers for the D mercury as well? And if so how many of them are there around? thanks!

Looks like a standard H tower.

Yes it is a Bonneville D tower. They were the same height as the H tower. I owned one for few years back in the eighties.
