TO THE GROUP

Well today I'm relaxing watching an old episode of Dragnet, and this
episode involves a drug smuggler who crashes his plane.

So here's Gannon and Friday standing beside it and I notice an N number.

To me the plane looks likes a Piper colt ( rounded rudder ) but in
another scene Sgt Friday says it's a Cessna..... I don't think so.

Anyways... my tired eyes and feeble brain might be mistaken but
I read the N number as N 97164 yet in another scene Friday
calls it N 17964.

So I'm kinda curious if some kind soul who has the ability to check out
these numbers could tell me what type of plane ( if any ) that those
two numbers come out as.

Please and thank you.
