mid century Hydrodyne speedboat pennant flag Crosby vintage ski boat or runabout

1960s Crosby vintage red and white Hydrodyne speed boat flag... 100% cotton canvas with a heavy chromed (probably brass?) flagstaff with 60s streamlined design.

This pennant is from an estate in the Wisconsin Dells area and so's probably from a water skiing boat, but maybe more of a Chris-Craft style runabout.

The printed pennant about 14" long, made by Taylor Made in Gloversville, NY. The flagstaff is about 11 1/4"(no bracket, sorry).
