Davide Pedersoli, one of Italy's oldest manufacturers
has had three logos since 1957. The earliest was a diamond
inside a circle. This is rarely seen. This mark was
followed by the image of an anvil with PEDERSOLI
above it in capital letters and the initials DAP inside the
anvil. This again is rarely seen, except on very early models.
The company logo, a lowercase dp within an oval,
has been used for more than 40 years. This logo is often
followed by the DAVIDE PEDERSOLI or PEDERSOLI
name in capital letters. In short, there is no mistaking a
Pedersoli product!
