[ARC5] Question on 'Eureka beacons'

[Hubert Miller]

>From Wiki on "Eureka beacons" :

"In December 1942 Brown was flown to the US via Pan Am Clipper to meet with the US I Troop Carrier Command.[9] They started production of a number of versions of the Mk. III as the AN/PPN-1 (Eureka), AN/PPN-2 (Portable Eureka) and AN/TPN-1 (Transportable Eureka). The AN/APN-2 (Rebecca), also known as the SCR-729, used a display that saw use for a number of purposes."

I had never known of the AN/TPN-1 set, altho in the distant past, I owned a complete AN/PPN-1. ( Now worth real money. ) 

Similarly to the above, does this mean there was a "transportable PPN-2, named the TPN-2" and that my TS-233 / TPN-2 was for maintenance of an AN/TPN-2 Eureka beacon ? ( Pathfinder beacons for airborne troop planes. )
