Hi EW,
Could you post other photos of your magazine...
1. Showing both sides of the full tubes.
2. Showing both sides of the wood (from side views) including the retainer pins.
BTW...when your dealings with your seller are 100% completed, it might help others if you shared whom that outfit is.
If this piece was sold as "factory original" to you and you have that in writing or emails and you paid a commensurate price, the seller should have done more that just agree to take it back on consignment sales.
A threat from you to "expose" their name publically and other legal actions might encourage them to grant you a full refund...but then the gun will just go back into inventory and sold to the next unfortunate...
Or you may decide to let this be your "lesson learned" gun. We all have them in our collections.
Folks that say they do not are lying, in denial, or have sold theirs off to the next unfortunate...
A certain M1902 FB Luger went that way between collector "friends" and was metioned here on the LF by its current owner in an old posting. The selling "friend" was even arrogant enough to offer to buy the $ 6500 gun back for $ 1000...what a "friend", huh ???
On your gun, one area that may typically indicate a rework is the area just below the toggle lock on the right frame rail :
Here is one that fits my "comfort level" a bit more :
