I agreed to send for the letter and Chuck has responded with the research data requested.
Chuck confirmed that the subject Parker VH was ordered with 30" barrels, a Monte Carlo stock, 2-3/4" chambers and the right barrel may have been bored Modified Choke. Additional tidbit was that this gun was one of ten in the order, all with the same specifications.
Many thanks to Chuck Bishop for his timely response. I will now proceed with confidence knowing the gun's configuration is correct.
