This weeks Headache ??

There is a huge clue in this photo, which will give you country of origin?

"S" for Scotland?

Wingco.

No not "S" for Scotland, but an American university cardigan.
Another clue. " Today the company manufactures about a dozen models of industrial turbines yielding upwards of 30,000HP. "

I was mis-remebering a tri -motor in the East Fortune collection, which may be even more obscure than this. I suppose Ford Tri-Motor is too obvious?

Wingco.

"The ??????? transport followed the general outline of the Ford
trimotor, including the corrugated covering. In November 1927, soon after
the new trimotor's first flight tests, ??????? announced the start of produc-
tion at an improbable rate of two planes per week. In fact, ??????? built
only one trimotor in 1927 and had no sales until February 1928, when a
sightseeing company bought one plane for aerial tours of Yosemite National
Park."

Hamilton Metalplane ?

Wingco

Very close, about six months after the Hamilton monoplane was announced this aircraft came out ?????

The Pruden Transport?

Wingco.

Sorry, Prudden with two "d"s ?

Wingco.

Well done nice to see a new winner
It is the Prudden XM-1.
