Was there a particular time span when ex Dragoons were made? Or did it just run until they were out of the Dragoons?
No one really knows. Conversion date is impossible to pin down. There are a very few examples of converted Russian Dragoon rifles that ended up in Finland. And speculation (only) as to whether the Russians or Finns did them. And there have been a very few Dragoons (not converted) imported in with the recent refurb 91/30s. Some of them with Panshin bayonets!
