Harper1249 - Nice strike. Looks like a Type 2 cogwheel.

Thanks for sharing.

SF Cogwheel T2 on Scott 65. The cancellation device is showing wear by the thickening of the spokes.

Hi Fritz --

Those are some really nice SF cog-wheels -- and on some very nice stamps and covers to boot.

Back when I was a collector of general classic US -- before I started to specialize in the 1851–1860 3c issues -- those cogs were one of my favorites.

Thanks for showing them.

Regards // ioagoa
