End of Production Dates for Convairliners

In the game, currently, all of the piston-driven Convairliners end production at the End of 1965. This is very inaccurate. This data can be sourced on rzjets.net.

Last Convair 440 was delivered in June of 1959.

Last Convair 340 was delivered in September of 1955.

Last Convair 240 was delivered sometime during 1954 (to the USAF, last civilian 240 delivered in 1952. 

Do note, however, that 130 examples of 340s/440s were converted to 580s from 1960-1969 and 

38 examples of 240s/340s were converted to 600s from 1965-1968. These are not [yet] in the game, though, so there should not be any confusion from those variants.
