I would rather have "Anglais a la Birminghamou". The metal to metal fit isn't particularly good. Perhaps it has been taken apart and put together too many times I don't know. I would pass. For 20,000 Euro or USD I would search for second-hand Granger. Some years ago Hallowell & Co had very nice 20ga Granger SLE for kool $20,000. It did not sell quickly because unless it was made in London, Brimingham or Gardone typical buyer in USA doesn't know what they're looking at. Manufrance isn't Granger but they did make some that resemble Scottish round actioned game guns. Those Manufrance Ideals are very, very nice and unique looking. That is what I would search for.
