Yes, ...they are the same blank. They are also kicking around the finger lakes under a couple of names the last 20 years.
Carl Johnson, aka "old swede" had the jig for that spoon back in the `80's. By the time I met him in the early `90's he had closed up shop and sold all his stuff. He did keep 100's of blanks though and that's how I got onto them.
Good stuff, ......just like needle fish .. .... 2 7/8" spoons seem to be a good all around spoon in the fingers especially if they can run good at 2.0 to 3.0.
BTW,....do you know what the secret pattern is?
