A50 Royal Star swing arm length

[chaz]

just checking around the Bee today. the rear frame rails have been cut off and replaced from curved to Hexagon straight tubes.
measuring the swing arm Im wondering if it has been extended , mine is approx 24inches from swing arm pivot to centre of the adjusting slot, is this normal or extended?  .

Extended.

Below from 1966-68 workshop manual.

as a follow up question
is there a site where these drawings are available online , Ive been helped with B40 frame and the A50 swing arm, now looking for the taper on the footrests for the A50 Royal Star
