January 1940 Gas Trap Conversion......Restoration?

[browningautorifle]

And if it does show the 7th round stoppage repair, why would that mean its a restoration?

They were built up with weld and a restoration back would mean it would be ground down again. You can see the weld in pic one. Here's an article to show you, scroll down. Marines The M1 Garand: The First 400 | An Official Journal Of The NRA

Some guys would grind the weld back down but not always. The rifle could have been assembled from parts would account for the later op rod and barrel...

Others will be along to confirm or deny these points...
