My photo is from 1955.
I saw that, but don't see any date for the other photos...unless I'm just missing something. Entirely possible.
I found this on the HAMB:
"The car was continually modified over the years and was completely unrecognizable from the original in its final configuration. I have heard that it does and does not still exist, though for some reason I seem to recall actually having seen it at one point. I just searched some photos of mine and couldn't find it.
The final version looked much like an oversized home-built Maserati Tipo 61."
