Lautprechermanufaktur Heyder (LMH) is new Contact for DrBA Authorized Prototypes

Final Treatment of the WN300ALO Horn with Joha® Violin Varnish

My decision was to go for the oil varnish 1a product series for my WN300ALO horns. The company also offers many painting accessories to optimize the final appearance of their varnishes – company homepage:
