I own both a wonderful female Wirehair and a Lefever sleeved shotgun. Lefever did great work, but that was then. I don't believe the successors to Lefever still do it. I believe his name is Giacomo and is a Perazzi mechanic. My Lefever sleeve job is a DH Grade Parker ten gauge magnum, originally a heavy frame 12 gauge Damascus gun. It is a beautiful job. My little Wirehair turned six last Saturday and is a wonder dog in my opinion.
