I'll have photos of the Fazackerly shown earlier for y'all to pick apart. A "practical exercise", if you will.
It surely lived a sheltered life, until it was sold off. Probably in a crate full of similar rifles that had been in QM stores their entire service lives. ("First in-last out", sort thing.) Out of 4000000 WWII No.4s I wouldn't be surprised that 4000 might survive more or less "intact".
The rifle of this study was doing pretty well, until some collector decided to "pretty up" the wood. I even have a culprit in mind, as he was notorious for sanding wood on virtually everything he ever touched, including almost "new" condition rifles of all nations. Hundreds of 'em! Col. Bill...Errrrrr- but he's long gone now.
