Yamaha YSL-6430ii and others of that era?

I’m looking for a smaller straight horn, and hoping to find a good deal. I see some of these older yamaha horns from Japanese sellers that look nice, but have very little info online. The 6430ii has a .525 bore which I’d like, but that’s really all I can find. Any idea on how this horn or others of that era play?

Watch out. On some early Yamaha trombones the chrome plating on the inner slide tends to blister and flake off. You can't fix this. The edges after a blister breaks are very sharp and will wear at the inside of the outer slide.

That said, I'd look for something a little later, like a YSL 645, 683, or 630.

If you want something a little smaller, the 65x line (0.500 or 0.508 bore) are also good instruments.

The 6430ii is indeed a .525 bore but the bell section is 8.5inchs so I'm not sure if that fits your description of a smaller straight horn.

I can't seem to find any info on the 6510ii but you can try looking here:
