The Type Certificate number of 681 covered Fahlin models from D-562 to D-586, so even though yours is not specifically listed in that group it can be assumed to have been designed for use on one of the 75 HP engines listed.

That Type Certificate expired on March 26, 1957.

It should be 74 inches long.
