Borsalino "Cocisca", French Point Size 5 1/2, 2.9 ounces / 83 grams probably early 1960s. This hat was sold by Mauerer Vienna so for the Austrian market. The felt is very light weight with a fantastic Chamois finish and interesting "Ramarro" Green color (Verde Ramarro = Green Lizard). If you look closely you can see a stitched brim binding most likely applied for stability + protection due to very light weight felt.
Josef Pichler & Söhne Graz, 56cm, possibly later 1930s early 1940s (see below). The hat is in NOS condition but unfortunately the brim was trimmed down to 2 inches. It came with the 1930s light green JHS "Standard Crystal Velour" I posted last week and was sold by the same store Rudolf Hanus Wien so it could be from a similar time period. The overall quality of this hat is high and the felt is fantastic (color, finish, hand). Josef Pichler was a brother of the more well known Anton Pichler.
I found this B.G.H. advertisement in D.H.Z. (10/1/1919). The B.G.H. marks in the lower left and right corners show the same letter configuration. The mark on the right is the same mark. This proves that S.H.G. was made by B.G.H..
Berlin - Gubener Hutfabrik "Stammhaus Guben" "Aquila Beste deutsche Marke", Wool, 56cm probably 1930s maybe older. This Wool Stiff Felt was made Berlin - Gubener Hutfabrik (see below). Belongs to Stefan on the FL.
