You are correct that these are not font files. Type1 fonts for windows have the suffix *.pfb. They must also be accompanied by a metrics files. The binary version of the metrics file has the extension *pfm; there is another format with the extension *.inf, which can also be used by ATM Deluxe to install the font. To install a Windows Type 1 font with ATM Deluxe, you must have the *pdb font file, and either the the *inf or *pfm metrics file. Your *AFM file is a text version of the metrics file, and I have no idea what the *.dat file would be.
