Apologize for the late response to your question You would need to get a quote from the Browning Custom Shop. Not all O/Us can be fitted with dual guage barrels. Try the link below to contact Browning.
Depends on who engraved it, the pattern, the wood, barrel length, accessories, box, papers, etc.. A few thousand USD or so
The value of a 12 gauge Browning Citori Pigeon Grade is actually dependent upon a number of factors. Some of these factors would be the age and condition.
