As far as the O/U are concerned. I do not think this model was called pull. The better and earlier series was the Orione. The later series was the 190 & 290 series. This was a model developed by Pino Benetti. This is a lower quality gun than the Orione series.
The Orione series did not have choke tubes. The 190/290 series and the later less expensive guns did.
As far as choke tubes, I do not know if any interchange as at the time, it was not problem to get choke tubes from Bernardelli.
The later series I only imported a few guns as I was not happy with ejector problems I had with them.
Stay Well
