This RL Drake R-4, T-4X New Old Stock Cabinet Bottom, was purchased by me from the RL Drake Company when they shut down their Amateur Radio Product line.
This Cabinet Bottom is marked for the R-4 Receiver, and it will also work with the T-4X
This one has the later style Spackle paint finish.
I will include a full set of brand new, original RL Drake feet and bumps with this cabinet bottom.
This is a great find, and the only one I have.
