VINTAGE 1920s tall boots wanted

[Shinobichi]

Hi! Just wondering if anyone knows where I can buy a vintage 1920s-30s tall leather boots for men. They are sometimes called prairie boots, linemen boots, motorcycle boots etc. These are the tall 16 inch boots. I'm looking for a size 12 .5 OUTER SOLE length and 4.5 WIDTH at widest point. I hope someone can help me. Thanks
