Old aftermarket distributor

Does anyone know what the cross-reference is for this old style aftermarket distributor. It is smaller than the typical Bosch/VW caps. It has 2 1/4 ID. The Bosch/VW cap and rotor is about 2 7/8.

No idea. It may be an orphan. Most T distributor conversions use the Bosch Volksbuggen distributor from the 1960’s.
