The "handle" is only present on the N44 & N55 series, it does not necessarily mean that it is a 78 rpm stylus. Generally, the 78 rpm styli Shure produced have dark green grips as Coffee Phil
The blue stylus you have is the N74C (.7 mil 2-4 grams) which, although it may fit, will not work properly in the M44 or M55 series cartridges. If you compare the white and the blue styli side by side, you will see that the brass shafts have different angles.Coffee Phil
is correct, the N44-1 is dark blue and has a 1 mil tip but it should not be confused with the one you have. The N44-1 has a side "handle".
It's hard to see from the photos but it looks like they were re-tipped. Shure styli never (as far as I know) came with "square" tips.
I bought a used N44C on ebay recently and when it arrived I was pleasantly surprised to find that it had been re-tipped with a "nude" square shaft elliptical 78 rpm stylus
