No doubt you're right: from readme.lucida, by Walter Schmidt:

***
How this collection was created
-------------------------------
The font metrics, virtual fonts and .fd files for the T1 and TS1  
encodings were created using fontinst 1.928. [...]

The font metric files for the LY1 encoded text fonts, as
well as the metrics for the math fonts, are those that were
formerly distributed by Y&Y.
