I have this Tuckaway first version that puzzles me. It has the threaded but flat-topped back end and there is no white dot. The pen came in its original Sheaffer Tuckaway (eg small size) clamshell box. The cap lip has the common imprint that includes "Made in USA", so it likely is not a Canadian variant. Has anybody seen this Tuckaway version before?

I found this July 1959 Parker pamphlet that substantiates the findings mentioned above:

The 1959 Insignia is gold filled indeed. The 1959 Flighter has the single wide cap band. This changed to two cap bands the latest in late 1960 (December 5, 1960 ad from LIFE Magazine shows the International Flighter with two narrow cap bands).

There seem to be different views on the meaning of the "T" imprint. Made in Toronto is the oldest one but possibly not correct, see this interesting (though short) discussion:
