IZ ukes

In pics, I've always seen IZ with his iconic (60s?) Martin tenor uke. Did he have just that one, or a few of them, and did he play any other uke brands/sizes? I assume that some of the K-brands we know today weren't even around back in his heyday, but surely Kamaka was. It seems he favored mahogany tenors, with low-G.

I know his favorite Martin tenor was cremated with him, don't know about anything else he played. I got the Iz Commemorative a few months ago, it has a sweet sound.
