In the era of handtool woodworking when the drawknife was more commonly used, there were many small tool makers who may not have left any identifying marks on their work. Perhaps as Ernest suggests, “who made it” is less important than “what condition is it in?” And maybe that’s a function of who it was previously owned by.
Don’t take this wrong, but is your dad experienced in using one? Will he use it frequently for tasks that it is the best tool for? Using (and sharpening) a drawknife safely and efficiently takes some skill and practice, and until he learns that, he needs to be careful with it.
I loaned one to a friend once, and his teenage son and friends were playing with it, and one boy cut his hand badly. Maybe I’m just wary now, but I don’t loan mine out anymore.
