To me, the most interesting plane is the first picture. I believe the plane with the curved sole and iron was a plane to shape bannister rails. The half round plane iron shaped the top of the hand rail for a bannister.
The other wooden planes are all common wooden planes. There’s always the chance that one of them was by a famous maker, I couldn’t tell you from the picture. They also could very well be all hand made. There is a limited market for these because they are almost strictly collector’s items with very few people seeking them out for actual use.
The iron Stanley looks to me to be about a #5 or #6. A nice plane, but common as dirt. it looks like it needs some TLC.
The set is interesting mainly because of your link to the owner, I’d think. Also, by having a set, you get a better view into what our ancesters had to work with as they built this country.
