I consider those new details to be quite important in terms of price, but I would actually be surprised if that drum isn't completely factory original. I've seen a lot of poor edges on Rogers drums, and maybe more in the Fullerton era, but also plenty in the other eras too. I don't think we should be hesitant to correct drums that need it either. After all, these guys were all going for production targets back then. I've seen really bad edges from every company. Think about the misshapen shells on 60's Ludwigs! So if a drum needs a fix, do it, and you'll still have a great drum. There are firms who do incredible work on edges, like Chris Heuer in LA, and from what I have been told Precision Drum Company in NY.
So, if I wanted/needed a WMP Dynasonic, I wouldn't hesitate to pay a fair price for this one (and have done so on several occasions). I've paid $1000, $1700 and $2500 over the last 5 years or so. The highest being for one that matched my catalog kit. Then I sold it for even more because there was someone out there that seemed to want it more than me and because my catalog kit is actually shown with a COB Dynasonic. Way back in the 90's I paid about the same amounts. I've only gotten one wooden Dynasonic for $1 back around 1995, but all the chrome was toast. I had to donate a $100 COB unit to get the chrome corrected and only got $50 for the COB unit afterwards. LoL
I say, if you like it, bid at least what TommyP is recommending.
