New Departure 10 tooth cog

[lounging]

Hi all

I am looking for a few of these 10 tooth cogs with the ND stamp, with little teeth wear. but I am looking for the cog still on the driver with the dust ring since I don't know how to remove the pieces.

I am looking to buy but I have a ND 22 tooth cog or an 11 tooth cog I'll trade for two 10s. Or a straight trade with my 9 tooth or 18 tooth cog or other parts. Please pm me with pics and prices, thanks
