Trying again! Can anyone help identify the artists who made these three items?

I bought these lovely pieces over the years and cannot remember who made them. The first is a belt buckle with the initials JTN but the N is reversed! The second is a bracelet and the hallmark appears (to these old eyes) to be a salmon or a fish. The third is a large bracelet with a hallmark that looks, at times to be initials (P.R.).

Any info or leads will be and is, appreciated…

Go on - I saw them both on there, the JTN (Jerry T. Nelson?) and PR. Good luck. That’s a good website.
