Drop, cradle, and on/off ID?

[FlightMedic938]

I picked this up off EBay. I was looking for a smaller drop and a cradle and came across this.

I’m 100% sure the drop isn’t ACI. It’s heavy and high quality. Benchmark?

I was certain the on/off was a remote adapter someone had janked up to work in the cradle. I really just wanted the drop and cradle. Once I got it in hand though I’m not so sure. It’s like it was made for a cradle. There is a designated channel for 2 set screw to keep in secure in the cradle. So is the on/off and cradle some super early version of an of/off by ACI?

Later benchmark with the wrong knob

Is the drop Benchmark as well? Or just the on/off and cradle?

The whole thing is benchmark

Thanks Ecap 👍

I ended up tracking it down using Wayback. Benchmark PMI drop forward with a Benchmark Sporty Shorty On/Off ASA cradle. Wrong knob though. Hope the ACI one works
