Hello Scott , Sorry about your Father Passing ! As for the V Grade your pictures aren't the best but you have it right there with you ,give it a good honest looking over and Go to gunbroker.com and look up side by side shotguns and then click onto Parker Brothers Shotguns and compare the condition of yours to the ones on there ,you will find upwards of 300 or so for sale ! Pay less attention to the " Asking Price " and more attention to the ones that are actually being bid on and then click " Watch " and watch them until the auction closes and see what they actually sell for and that will give you a very close idea as to " True Value " ,Most of the VH Grade 12 Gauge Parkers in average condition these days seem to sell on line between $700.00 and $1500.00 ,of course there are those with high condition that sell for considerably more but without much clearer Photos you probably won't get many comments here to the Value of your gun ! The best thing to do is ,join the PGCA , with your membership you get a nice discount compared to a Non Member if you decide to order a Factory Letter for your gun also a Wonderful Quarterly Magazine and Great Fellowship with the other members of the PGCA , then get it checked out by a competent gunsmith and start shooting it and enjoy the Gift from your Dad !
