Capacitor Assembly MX-9027/TSC-60(V) Info Needed

[AJ1G]

Anyone have any info on Capacitor Assembly MX-9027/TSC-60(V)?  It followed me home from Nearfest some time ago, appears to be a matching network probably used for matching whip antennas on the Collins TSC-60 transportable HF radio systems.  Black box with Type N input and output connectors full of relatively small transmitting type mica or possibly fixed vacuum caps, has a series or shunt switch and  a multi-position rotary switch labelled with frequency bands and SWR ranges.  Would be just the thing to use with my new 40 meter vertical / 75 meter inverted L with raised radials.  At minimum a schematic would be very helpful, at best some sort of tech manual or tech manual extracts.  Have not come across any info on it from what tech info is available on-line for the TSC-60 systems.
