Mako 22...that looks reminiscent of those "Riptide" jigs that used to be sold around here years back. Think a guy in Campbell River made them.
Are they back in production?
No they are called Metzler Mooch-A-Jigs. Norm Metzler, a friend of mine here in Port Angeles, marketed them for many years. They were cast in a foundry in the Puget Sound Area. Out of production for many years, Norm and his Sister have started up a very limited production, now cast in I think Bellingham. They were designed and patented by Norm's dad back in the 70's I think, somewhere I have a copy of the patent.
They are hard to fine, I bought a dozen from Norm last year. Have not seen any in our fishing stores.
Turn it sideways and it is banana shaped. Hollow, the leader passes all the way through. I will take a few other pics and post.
A very good jig, the one shown is 6 oz, I have them up to 12 oz. The 6 and 8 oz ones are my "Go To" jigs, on Coyote (Border Bank) and our "Rockpile" which is south of the boundary and about 6 miles north of Ediz Hook. I have caught lots of salmon and many halibut on these jigs.
When you drop them to the bottom they fall flat and the convex side hits the bottom first. A good jig is battered on the convex side as a result of hitting the sand and rocks. I drop them to the bottom, reel up 5 turns, jig a few times,drop back to the bottom and repeat.
