[Boatanchors] 5 receivers

Drake 4-Line

What about the Eldico R102 (with a full rack or rocks) or the Allied AX/SX series?
I dunno.  Comparing to a SP600 (and especially the later variants) thins the herd very rapidly...I know there are plenty other GC receivers, but not many with the performance of a late SP600 AND the light weight and size of an R4C...
I have a clean R4C in my pre estate sale.
