Just another point to ponder,
This machine was made in the early 1970's as it has the double ID plate set up as I mentioned in an above posting, so I'd be comfortable in saying it was around 1971~72.
Also that "Lawn King" Decal on the catcher is about one of the best surviving units around as most are damaged in one way or another. I'm pretty sure that it is a clear background decal which pretty much has protected the paint underneath from fading.
It would certainly be worth taking very accurate square on photos of it for future reference and duplication for Grant (willingworker)
Cheers,
