I picked up a Wards Master combination plane a few weeks ago. All of the research I've done says it's identical to a Stanley #45. I bought it with the intention of using it as a plow and dado plane, thinking it would be easy to find some additional flat blades.

Oops.

I've found a couple of flat blade auctions, but they're not the sizes I want. Does anyone offer new, ready to use replacement blades for these things, or am I destined to haunt Ebay for the next few months only to wind up with a blade that's seen better days?

FWIW, I've got a 5/8 blade. I'd like a 1/4" blade, and perhaps a few other smallish sizes.

Thanks!
