Taillight identification – Hupmobile?

[Tom Burtch]

This housing is about 4 ¾ inches in overall diameter and is mounted to a stand by three bolts that are around the electrical connector plug. The STAUB marking should identify the application but I don’t see this listing in my reference materials.

I have found on-line information which indicates this light was used for 1929 Hupmobiles, but I’m not sure.  This housing is uniformly round with no styling line at the top.  I thought that Hupmobiles in about 1929-30 used a styling point at the top of the rims which carried back to a slight ridge on the top of the bodies for both headlights and taillights.

Does anyone recognize the STAUB code and know the application?

Thanks,  Tom
