Don't know if anyone else has posted about this, but while wasting time on epay I came across this item 170539617416.

Mercury M335 1957 Turnpike Cruiser valve covers. Very neat covers but a little pricey, however that could be because of the wide range of years and engines they fit. 1952 to 1960.

They are neat looking valve covers though.
