I found some information in the catalog, link below:

According to the Elbel S-8 catalog. Very rare. Condition: EF (excellent) with patina. ($6,000), but in my opinion it should be more expensive due to its rarity and unavailability.

Rarity does not equal value, you also need enough collectors to want an item. Not sure how high demand is for such an object, to me the price given os already very high.
