Overall, it looks like a nice iron that will clean up and display nicely.
I would tend to keep it since it is an uncommon early old iron. Not rare, but uncommon.
If it was me, it would really come down to how much I paid. If I paid top dollar for a pristine iron, I would be looking for an adjustment or return if that is possible.
If I got it for a steal, I would not hesitate to keep it.
I don't know the market for this iron, but I would expect it to fetch a decent amount in good shape.
