Civil Registrations, 1927-1946
(Also 1946 and later, but in development)

This major works by the late Lennart Johnsson was based primarily on original extensive research by Vincent J Berinati, and began many years ago as handwritten data on 3"x5" cards. Only recently were the data transcribed into computer form.

    It should be noted that the "Johnsson Big Book" presents US numbered registrations ("licenses," if you prefer) only up to World War II—except for some random exceptions—and does not show prefix letters (C, X, NC, NS, NR, etc). Post-war registrations will be an equally monumental work and has, to our knowledge, yet to be accomplished in depth and accuracy. What you see in our secondary, follow-up works is very incomplete at this time.

    A brief explanation about how the U.S. system of registration was created is found on the Numbers Racket page. It's a good basis for understanding how governmental minds dealt, or tried to deal, with a complex issue.

Format - After the registration number the name and model of the aircraft are shown, as well as some motors of interest (in parentheses). Following a comma is the c/n (constructor's number). After a dash comes general info, such as builder's name, subsequent change of model designation, re-registration, or remarks of interest. These "comments" are purposely brief since general information can be found in the individual entries of those aircraft in AeroFiles' main pages. In these remarks a right (>) and left (<) pointer should be read respectively as "to" and "from", showing the path of certain aircraft to/from another model, c/n, or registration. N* indicates an occasional post-war registry. Question marks mean just that—data are unknown or suspect.

Duplicate reg numbers - These occur when a registration was cancelled because a plane was scrapped, destroyed by accident, re-registered with another number, or sold out of the country, and its number was applied to another plane.

"sub" - This tag on a c/n indicates that the owner substituted a number differing from the original c/n stamped on an aircraft's nameplate, such as for a rebuild or mod.

So, here is a quarter-century's worth of work to keep you occupied and out of trouble for a few hours...
