Can't find any information on these 2 planes. They are marked W J R 1958. It's the only marking on the tool. The bottom of one is slightly curved, second plane has a pronounced curve on bottom. The irons are very thick, over 4mm. Anyone know of this brand? Why the curved sole?IMG_0874.jpgIMG_0875.jpgIMG_0878.jpgIMG_0876.jpgIMG_0877.jpg
