Hi Baumy,
The sticker yours has is the later sticker that was used on the Briggs and Stratton engine line up and the last Kirby's.
This proves that yours is a late 1975 machine with its original engine just prior to the engine line up change over.
One of our members "willingworker" has these decals for sale so it's probably best you contact him via the PM feature on this site.
Just out of interest, the artwork used on your transfer was a direct copy of the decals used on the original 1968, 14 inch Briggs powered Model 45 while all the other size machines used Kirby's with those other HP rated decals. Odd isn't it ??
Cheers,
BB.
