It is indeed the 357A. As I had said, it initially did show 1760KB. I finished cleaning it out and putting it all back together (talk about a pain, needing to pop out the Radeon and Network, then Mediator, then CD-ROM, etc...)
It is now formatting at 1760KB.
Out of curiosity, I just did a google for Mounting RAD, but most people said it didn't survive a warmboot, so how exactly would I use that instead?

Just type "mount rad:" in a shell window, or double click the RAD icon in dh0:storage/devs/dosdrivers
It survives a warm reset, and you can change the size of the disc by editing it's tooltype.
It's very, very, handy.
