Seattle Film Works Process SFW-XL

I hate to admit it, but I founds four rolls of exposed file with
Process: SFW-SL on the canister.  Where does a person send these to get
them developed?  I searched several photograph news groups but there is
very little information that isn't over 6 years old.
Any help would be greatly appreciated.

Some advice that I find says the film is old movei film.  Others have
stated that it is C-41.
The local labs won't touch it.  What is a person to do to get these
rolls developed?

Thanks in advance,
