Ok....the SKS ACOG is ridiculous. But what kind of dumba$$ does that to a Johnson?
IMHO, that would depend on the condition of the Johnson when the smith did the work.
When those rifles first came into Canada, through Century International in Montreal, they were from offshore warehouses, where they were either left behind by US Marines or given to as Lend Lease.
They weren't allowed to return to the US as complete rifles but the parts weren't under such restrictions, other than the receivers.
Before Century started to strip them down, they approached the major firearms dealers across Canada to see if they were interested in purchasing the rifles in quantities large enough to be worthwhile. I believe, it was a long time ago, that the minimum order was 100 rifles, which was the equivalent of a full pallet.
Allen Lever was quite excited about them and we made the trip to the Montreal warehouse to see what we would get for the money, which was pricey for the time.
The condition of the rifles overall was quite good, ranging from Good to Very good for the most part, with a few hundred looking close to excellent.
That was what they appeared to be on the surface. We were allowed to fully inspect rifles from a randomly selected pallet from each ''grade'' and base our orders on what we saw.
This wasn't the norm but we had seen it before and the people at the warehouse were usually pretty good at assessing conditions.
In every grade there were rifles with shot out or badly pitted bores. Some were not functioning etc. Pretty much standard for such stockpiles.
Sidney I Robinson got there before us, which was also normal and put their placards on the pallets of rifles they wanted. They too, most of the excellent grade, but none of the other grades.
Lever managed to get four pallets of excellent grade and six pallets of Very Good grade.
We left after that, but not without checking the other grade. which was all marked "GOOD ONLY"
There were also bins of parts that were left over from warehouse stocks or had been stripped from rifles to make up many of the rifles in the "Good Only" grade pallets. This work was done in the UK, before being allowed into Canada.
In those days, it was still legal for Canadians to purchase, own and shoot full auto firearms. There were several Johnson machineguns in crates with spare parts kits available as well. Lever didn't purchase any that I know of.
There were enough parts in those bins to assemble a few hundred fully functional rifles, but condition would have been POOR at best when rated overall.
The rifle in the pic could easily have come out of those parts bins.
Whoever did the work, it's very good.
