S/N 875 first flew 13 Jan 1941. The assembly line was smoking in early ‘41!

There are more projects than there are airworthy Collegiates. I try to match them up with new, enthusiastic members as I learn of them.<br />
<br />
The Collegiate type was beloved by CPTP cadets, at least the seventy or so that I spoke with, back in the 70’s and 80’s, who had learned to fly and soloed in them. Her downfall was the all wood wing. The Grade A fabric would start to rot and the wood within would soon follow. Those who had never been charmed by her flight characteristics feared the integrity…

The Grade A fabric would start to rot and the wood within would soon follow. Those who had never been charmed by her flight characteristics feared the integrity of all that spruce and shied away from buying them, so they rotted into the ground after being stripped of engine and instruments. Even her Shinn wheels and brakes were thought to be inferior to Clevelands and Goodyears. Ignorance has always led to poor decision making.

<p>Thanks Andy, the more I read about the Porterfield the more intrigued I get, but I’m also learning there isn’t an enormous amount of information out there. Thanks for the heads up on the FAA database, not a huge amount of these birds out there, I assume that not all aircraft on the register are necessarily flying either?<br></br> <br></br> <cite>Andy Gelston said:…</cite></p>

<p>Thanks Andy, I appreciate the reply. Thought there must be some method behind the numbers. Do you know of any literature that would help me research my serial number to see where it fits in the production line?</p>

<p>Serial numbers don't necessarily reflect the quantity produced, Steve. The Collegiate series started with s/n 550...the CP-50 prototype, but when it was upgraded under a different type certificate (A720), the serial numbers started at 651. However, the one seaplane built (Kevin Feauto's restoring her) has a s/n of 981: go figure!</p>
<p>The CP-40 Zephyr series started out with s/n 250.</p>
<p>The Model 35 Flyabout prototype was serial numbered 101.</p>
