There is nothing wrong with posting closed auctions, or some auctions where there are perceived problems, - or in some cases for educational purposes where the likelihood of injustice (bidding against/unwarranted compitition) to a member here is low...
In this case I think I would characterize this auction valid for posting for the latter reason... no need to go into my concerns as it is over, but if any body here thinks to buy a rifle like this for $4000 or any G98 for $4000, you really should ask for another set of eyes to look it over and give an opinion...
Hopefully this rifle will surface at auction or somewhere where I can confirm or dismiss some concerns, but these pictures are inadequate for a $4000 purchase (imo)
