From the German & Austrian Violin Makers by Karei Jalovec. Born 12/3/1896 in Erlbach. Established himself independently in 1922. He made first-class bows. He used 3 different methods of branding his bows: *GERH. WALT. RENZ* with a shallow impression of the stamp; for the best bows of the series, the same brand but impressed deeply; and for his silver bows, the brand W.RENZ without the asterisks.
