too shiny??? that is not usually a problem and something easy to fix otherwise

The seller seems to think they go on the chainring side, but he is wrong. They go on the left side. They are shiny because they are NOS, but the 7/16" x 24 tpi size is correct. If the crank pictured above is yours, then it is the one you need.

Sand it with 1000 grit paper.

Are you sure they're wrong? The auction does state it is for Earlier Iver bikes which did have the nut on the chainring side (like the 1910 you have) I don't recall the thread pitch, orientation etc. on either nut.

Yeah, he states it goes on the chain ring side, but then shows a pic of the left side crank arm? So I don't think he is sure which side it goes on. I have never dealt with a later set up where the lock nut goes on the left side, but it makes sense that the left side would have left hand threads, yes?

Hard to tell. Do you recall if your early threads are right hand or left? The left side nut is left hand threads. It also has a step to it which the eBay nut does not have. I wonder if these are actually Iver nuts?

See how it covers the entire flat face of the crank arm.

You are so right. I now have to say that I don't think they are Iver nuts after all. The early style do have steps and my crank side nut is right hand thread. I wonder just what they are for then?

I'm Afraid that this one on Ebay will not work. You need a left hand thread nut and he says that his are right hand thread.
