Odd Rear Cogs - Racecycle or ?

[oldspoke]

Hello All

Would anyone be able to I.D. these rear cogs and what cycle they may have been used for ?

1/2 inch pitch and they appear to be left hand thread,

They look very similar in construction to the large rear cog on the Racycle Pacemaker pictured in the thread of "junkhunter".

These came in a box of bicycle bits.

2 cogs {32 tooth & 28 tooth} are shown with both sides .

Thanks for any thoughts.

They look different thread sizes in your photos. I was thinking maybe the larger of the 2 sprockets from a Hirondelle 'retro-direct' system, but the cut-out shapes don't look quite right.

This was the Cog on my 1904ish Racycle - just a FYI

Have zero ideas as to what I'm lookin' at.
If one or both are available .. I have cash
or trade. Hopefully (if available), they are
cheaper than diamonds of equal weight.

It is my understanding (through rustjunkie)
that ND and Musselman are using the same
thread recipe .. while Morrow continues to
go rogue.

Don't have paypal ... but know how to make
cash take wings.

Lemme know ... thank you !!
