Hello Mike,

Forearms only slide forward to remove the barrel assemblies and are not removable nor interchangeable.
Each barrel assembly has its own dedicated forearm assembly.
All barrel assemblies have standard Browning ribs between the barrels and standard Browning narrow ribs.
Each barrel has complete Belgium proofs and are marked Made in Belgium.
They are also marked Browning Arms Company - St. Louis, Mo.
This is a 100% Browning built gun, no Simmons or aftermarket work, hence the reason for the original post. This is the second early Browning smallbore three barrel set I have owned. The first is now 5 figures and I wonder what this one is worth, seeing as how people tell me that it wasn't made and then want to pay me a pretty hefty price for it??? The set could have been made up by Browning at a later date, but how does that explain the exactness of the serial number stampings on all three sets of barrels??? Inquiring minds want to know!
