The 120/10 240/10 40/10 40/10 ?  A little math derives  12 24 4 4

The LensID is a two-byte integer. Pentax PEF files are stored "big endian", so 4/248 would translate to 1272. But it's just a unique number that Pentax assigns to lenses. If you look at the following URL, the exiftool folks have decoded quite a few of them:

The "LensInfo" field is an array of at least 16 bytes. They haven't figured all of them out, but the following URL will show what they have figured is in those 16 bytes:
