Details:

Both have same construction, see pictures. As you probably know Cunningham was absorbed by Rca. Tube envelopes are clean and no flakes or burn marks. Label is better on the Rca than Cunningham, but there no doubt these are same construction.

Good luck buying. No boxes available these were found loose piece at a ham fest. Vintage pair of Radiotron black plate 2A5G tubes, both test good on my triplet 3444.

One is branded Cunningham Radiotron, and labeled Rca Radiotron. Bases are good no cracks.
