I suspect that my made in Italy “Rottweil” .410 over and under was made by FAIR.
The mechanism on the lumps and ejector work appears identical to the picture posted by Stan of a “Verona” FAIR (?) 28/.410 over and under on the thread “Good starter over and under in 20”.
Having said that I would appreciate any more definite information. It was made in about 2007 and I purchased it second hand.
As that was not long before lockdown I have only had a chance to shoot one round of skeet with it thus far, but it seems to be well made and the online reviews were encouraging.
