The Gl-5J29 is magnetron that requires an external magnet. This split anode design predates the cavity magnetron that was able to generate vast pulse powers.
The anode loop is water cooled and the 5J29 is designed to operate between 350 and 770 MHz. The input power is around 500 Watts and the conversion efficiency is 20% giving an RF output of 100 Watts.
The solid filament pins and the hollow anode pins.
The filament is a single rod of tungsten. The anode is copper.

The wide glass tube envelope is 51 mm in diameter, and including the base pins is 165 mm tall.
Reference: Data-sheet. Type 5J29 was first introduced in 1946.
