Earlier this year I found a very high condition A5 Sweet Sixteen that was delivered to the Browning warehouse in 1949.
I have only shot some pen raised Chucker’s with it but I really like how it handles and now know why it’s called a Sweet Sixteen.
Shortly after I purchased it I ordered this book. For About $90 it’s well worth the money.
