Does anyone know the manufacturer of the "AW filter" petcock used on early BMW and Zundapp. The insignia is a stylized "AW" surrounded by a cogwheel similar to very early VW and KdF designs.

They are still made, the

They are still made, the Frankfurter Modell petcocks. I am not sure who has the dies/tooling but I bought two of them off of Tillmanns. A few other vendors on eBay have them for sale as well. I have had them installed for 6 years with no need for rebuild. Those petcocks are way better then the Everbest style.
