Springer
PUMA Springer, the model number is 983. This is an extremely rare model that is pre 1964. This model has a unique opening feature, much like a switchblade. PUMA only made few of this model every few decades. PUMA first began making the Springer in the 1950’s. Later on the model changed to the Springbock II.
The Springer was made with stag handles. PUMA made the blade with carbon steel as well as stainless steel.
I am currently chasing this model.
