I found this frog at a pond I was fishing recently. I really like the size and it still casts well (the body is 45mm-50mm long). Can anyone tell me what lure this is? Does the belly weight look custom made?

Hard to say. It has the raised arms, but its not a Koppers. My best guess is that it is a house-brand or knock off of some kind.

I'm 99% sure it's the Dicks Sporting Goods House brand (Jawbone) frog.  They run like $3 each

Looks like it's the color "Frog"

I rummaged thru my frog drawer but the closest match I could find was an old Spro frog.

It has the same walking weight in the same location, has a diamond shaped underside,

and a circular dimple behind the eye. Possibly a forerunner of the Bronzeye, but I really can't say.

Jawbone Frog.

Pretty sure it's a Jawbone frog as well.
