Part Number I.D.

[studesnbldr]

Can anyone assist me with the two following part numbers? I cannot find them in any parts books I have. They appear to be '57-'59 era Hawk switches, but I'd like to determine their specific applications.
These are as printed on OEM boxes.
#1544393
#1554978

Were these numbers perhaps superceeded?

Thanks in advance.

In my March 1, 1963 book F both numbers are still good. I'll look later in my '66 book I don't have it here.
