Don' t buy either new unless you absolutely need a bespoke gun - Spanish guns have experienced a lot of price inflation recently for various reasons, and an equivalent used gun in 99% condition may cost 30-40% less.

What is your budget - that will affect the answer to some degree. Also, there are a lot of Arrietas out there with Orvis or G&H markings. Often, those guns go for less even though they came from the same factory.

Such a long, long time to be gone, and a short time to be there.
