bczrx,
I was hoping someone else with knowledge of J.P. Sauer s x s shotguns would have responded to your post with additional info.
The 1957 Shooters Bible lists two Sauer s x s models:
Sauer Model 8 DES available in 12 or 16 gauge with a selective single trigger and ejectors priced at $ 355.00
Sauer model 8 available in 16 or 20 gauge with double triggers and extractors priced at $ 148.00
Same model with ejectors priced at $ 238.00
All were available with Arabesque engraving
The catalog also showed better engraving available.
