Wanted: WTB Browning Auto-5 18.5in-22in barrel

Hi all, looking to get my hands on a shorter barrel for my auto-5.

Mine is an old school Belgian gun in case there are differences with the newer model. Will pay up to 400$ depending on condition and could send a 50$ "finders fee" if someone helps me locate one they dont own!

Will also buy spare parts you have :)

Thanks!
