The International Cessna 170 Association

There are some very interesting manuscripts within WSU’s archives. See especially Wallace Cessna Aircraft Company Collection. They have production cards for several different models but, unfortunately, not for the C-170.

Actually, I've found one card for a C-170. It's filed with the C-180 cards. Like George's plane, this one went to Central America. But what's weird is that it is s/n 24000. According to Cessna there is a gap in production serial numbers in 1952. This gap would be serial numbers 21000 through 24999. This plane, s/n 24000, was delivered to El Salvador in 1956.The following aircraft, s/n 24001, was a Cessna 325. What the heck is a 325 you ask? According to Thompson,

An agricultural version of the L-19 called the Model 325 was first flown by R.L. "Bob" Crawshaw on January 31, 1955. It featured a tank for dust or spray materials in place of the rear seat, a 230 HP engine, constant-speed propeller, and larger tires and brakes. Only four units were produced for evaluation by a selected agplane operator in Stuttgart, Arkansas. Since the market was judged to be inadequate, the project was dropped in 1956. (Cessna: Wings for the World, pg.179)

In our Directory there is at least one additional C-170 that falls within the s/n 21000-24999 range: N1896C is s/n 24061 and is listed as a 1952 C-170B.
