BEAVERTAIL crank
has gear ...
has woodruff key
29.2 lbs
weighed on a $200 shipping scale.
Too cold to measure main and rod size.
Fifty years ago an old time racing guy told me that this was a good crank for a racing engine!
He said with a big smile:

:
"The Beavertail crank cuts through the oil vapor easier and has less air resistance!!
I took that to mean that he was joking!
