Early hub cog swap

[gtdohn]

Will a rear cog from a Musselman hub fit a Morrow hub from the same era (1910s)?

That's a good question. If I thought my armless Musselman would come apart without damage, I'd try that out for you. May need pictures to show which hubs you are trying to mix though. Track hub/cog threads are likely interchangeable, but coaster brake hub cogs may not be...as I know ND Model A and Morrow/Eclipse are not the same. They are also different thread diameters than the track hubs.

They are both coaster brake hubs used on racycles in the 1907-19teens. The cogs in question are both 12 tooth.
