Italian film set in 1910-1920s with great suits

[Rittmeister]

I saw part of an Italian film on Italian TV (maybe made for TV) that appeared to be made recently about a police squad fighting gangs. It was set about 1910-1920s. I remember that all of the police were wearing great period style suits with contrasting vests, high collars, great hats. The period detail was excellent: cars, interiors, etc. Does anyone know what film this is? Thanks.

dunno, but sounds like an Italian version of Boardwalk Empire or Peaky Blinders.
