G'day Max, Voytek S and all cone clutch lovers
I wished I had never said that that clutch lacked engineering sense.
I should have said it made no sense in Scott Bonnar history.

I have since learned that Scott Bonnar did use a friction cone clutch
for reel protection on their post WWII Model 19.

When you refer to "Model 330026" the "0026" is not the number on the name plate, Is it? (My mover has a "33 2887" number on the plate.
That's right, Scott Bonnar were not consistent here.
What you have is a mower serial number.

I'll see what I can find with better resolution pdfs.
Give me a bit of time.

Max, sincere thanks for the Royal Blade images. Brilliant.

The obvious question is why did SB abandon the 33 clutch
when it introduced the Model 45?

Maybe the answers goes to the properties of cast iron
versus aluminium. Any ideas?

Cheers
