Old crane cam help

Come on you two. Do we have to see this on every thread now?

To the OP, you MIGHT try an old Cam Dynamics catalog if you can find one. Crane made that line too and it could be one of those old numbers. Cam Dynamics also used the same prefix or suffix such as "HMV" as well, although it was only stamped on the cam and not advertised on the part number in the catalog.
