Hi Tygger2 and welcome to GVR.
While vintage HP testgear isn't my field I'd say it was 1960s, not 1950s. See this video: https://www.youtube.com/watch?v=usDpuNZMcpk
Since it looks similar to the '45L there's a chance of some commonality. It will become obvious once you have the covers off.
Some notes on both instruments here, including noting some differences: https://www.antiqueradios.com/forums/vie...8&t=214192
