There was a very good thread here on ASSRA where we discussed the Type 33 and 33a Husky rollers a lot. But I just tried finding the old thread with no luck. 
I own a Type 33A in 9.5x47R that's very close to .38-55 and I use that brass and dies to load for mine. Mine needs smaller diameter bullets so I use .376" bullets in my slightly shortened cases. I'd guess yours needs to be slugged to know exact groove diameter, and a chamber cast done to get an idea of what donor brass will work. Likely .30-30, .32-40, or .32 Win. Spl. brass may all work once you know the length and shape for sure.

Here's another link that has some info also:

I have one that I really need to do a chamber cast on, plus slug the bore.

I’m fairly sure mine is a 9.3x57R, otherwise known as the 360 2 1/4, but all that remains to be seen.

I will have to dig out photos, or perhaps take a few new ones. 

It is very petite and elegant in comparison to a full size rolling block.
