Browning A-5 Serial Number & Manufacture Date?

I have a Browning A-5 that was my grandfather's upon trying to do some research on it I located the Serial Number. It reads 46121 and under it C47 by looking online i have come to the conclusion that the gun is circa 1926. When I found this out I almost literally ped out. If I could get a 2nd opinion I would greatly appreciate it. And also about how much would it retail for? It is in Good-Great condition with just normal wear scratches on it with no scratches on the stock & foregrip also the wood on the gun looks as new as my 2008 Remington 11-87 that hasn't been shot more than 25 times yet also. Any help greatly appreciated!!!
