I would start with the colonial. If you give some blade dimensions I have several sets of scales for those as I used to collect them. If I don’t have a set that fits you can make your own. They’re solid shavers and generally easy to hone. Making scales is very difficult business until you understand how they work. Making them provides you with a much better understanding, reading and theory only get you so far.

For material I have those blades in bone, horn, Bakelite and plastic. They are fairly common.
