Skellenger gears please help

[steve g]

I have a pile of skellenger gears (I think) they all look like these. My problem is they are all mixed and I’m trying to figure out how to match them... any ideas?
Thank you.

That's not a pile of gears? Looks like 5 matching sets? !3/27- 19-21 is the range. If gears are 1/4" thick you will need the 1/8 " spacers.

Gears came in two thickness. 1/4" to reduce weight and to get more gears from bar stock and original 3/8*" Both styles were heat treated.

That’s what I was looking for! Perfect thank you!
