Wow,that is one shiny tall cp!

I sorted a few parts and thought it would be fun to create a smiley from SF240 parts.

It is a 5,25 mm cannon pinion, gen.

Guess which set of wheels are gen and which comes from my work, left or right?

[TUFF Stough]

judge by the sunburst finish on the gear, my guess is left = gen, right = yours

am i correct?

expect no less from a skillful watch maker as you are, Sir.

am i correct?

I'd say left gen because of the lack of inner edge finish

Me being me I saw the tree but not the woods, LoL. The smiley is the best!

You were both right, the pair to the left are gen, congratulations!

All four do actually have the sunburst pattern, the light and the angle may be disturbing, perhaps even a bit of oil or greasy fingers.
I did go a bit further and polished the edges a little, good eye.
