This poor broken exhibit is a Philips 1129 gas filled battery charging rectifier. It appears to have two carbon cylinders for anodes and a central plate with a grid like structure above. Also inside is a small coiled loop.
A closer view. The fact that the pinch broke but the envelope remained intact is suprising.
Behind the left structure is the small coiled loop.
The balloon envelope is 70 mm in diameter, and excluding the B4 base pins is 114 mm tall.
Reference: Datasheet. Type 1129 was first introduced in 1954.
