You, my friend, are one lucky S.O.B! If it had been me who dropped the razor, the scales would be perfect, but the razor would be shrapnel...

You can find good Filarmonica scales on Ebay for cheap if you look at some of the razors that have less than desirable blades. I don't think this is something you can find new as replacement parts.

One of the restorers/honemeisters on this site may have a set languishing in a drawer somewhere, but buying a busted Fili from Ebay and switching out the scales might be your best bet. Good luck!
