I have a Dunlap #3, with a West German iron. I looked behind the frog this morning, and saw the threads of the frog's bolts. Frog sits very nicely on it's base, makes decent shavings, and no chattering about when on the job. But to look in the area behind the frog and see an 1/8" gap? A look at this little planeSDC14315.jpg Used to have bright RED painted handles, now has BLO. Seems a few of this style were made, either as Dunlaps, or as Fultons. I will take it apart later today to look a bit and see IF there is anything hiding inthere but haven't seen anything...yet. Just a little $8 #3 plane. Sargent made???
