Well apparently you do - your father found them.
Sorry could not resist a leg pull.
Many companies made tools for the big stores, Sears, Wards, even some of the big hardware stores. They had the "store" label.
Some of these were very similar to the Stanleys at the time, frequently some features omitted to save price.
There are a lot of no-name around. If you get this you may find some stamping on the blade, sometimes no markings at all.
The middle plane is a transitional - as in these were part metal - the portion to hold and adjst the blade - and part wood. In between the wood planes and the later all metal planes.
Transitional planes are loved by some, and hated by some. I had one, and did not like it so I passed it onto Chris Curl who does seem to like it.
These are potential users, but you may have to put in some elbow grease to tune them in order to get decent performance.
Frequently the old planes have bad sharpenings, or have not been sharpened for a long time.
If you can get these, they are worthwhile to have, even if only to learn about tuning planes, sharpening blades, etc.
