I have an HP 5245L Counter, late S/N with the following Plug-Ins:

5253B 50 - 500 MHz

5254C 0.15 - 3.0 GHz

5265A DMM

ALSO: Comes with a working parts unit for spares. Looks like %^&$ but
it does work.

I may have an original manual for the 5245L somewhere.

$50 the lot, BUT you gotta come pick it up. I am in Lexington, MA.

Don't ask me to ship it, you will not like the price.
