It's an English nickname for small grip C96. Commonly referred as "Bolo", or "Bolo Mauser". Most of Bolos are 10-shot with 4" barrel. Small amount of them have 5.5" barrel, and rare variation were 6-shot.
The origin of the nick name is a myth. Saying this type of C96 was Russian Bolshevik political official's favorite in 1920s. So it's called "Bolo". But in today's classification, no matter small grip C96 being made in pre-war era or in 1920s, it's called "Bolo" as long as the grip is small.
Bolo were used extensively in China. One of the best known Bolo was the one in this 13-minute video (with English subtitle):
