Found this on a Spanish website:

- August WILMSEM, Sargento del Jagdgruppe 88, muerto el 01-06-1937 en Larrabezúa (Vizcaya) al recibir un disparo cuando se arrojaba en paracaídas tras ser derribado su Henschel Hs-123 ,probablemente deribado por la AA mientras atacaba el "Cinturón de Hierro" bilbaíno.

Translation:

- August WILMSEM, Sergeant of the Jagdgruppe 88, died on 06-01-1937 in Larrabezúa (Vizcaya) when he was shot while parachuting after his Henschel Hs-123 was shot down, probably shot down by the AA while attacking the "Belt of Iron" from Bilbao.
