Is it just me or does it seem that perhaps two different engravers engraved the sides?? Patterns are similar but appear executed in different manners.
Odd looking stock on the 86,,maybe it's just the lighting in the left side closeup shot,, I'd go with Steve's '73 anyway..
The appearance of two different engravers comes from the smaller size continuous scroll being cut on the loading port side.
The pattern uses a large full scroll on the left side. With that you can put more detail within those large scrolls. Smaller scroll, leaves curling back on themselves, ect.
When you go and cut the same style on the right side you're stuck with small thin areas to work with-in.
No large scroll,,just small uninteresting simple scrolls that never develope in a go-nowhere space.
They just unwind one after another, all the same size and boring look to fill in that narrow space.
Little can be done to liven them up w/o drasticly changing the look of them from the other side.
A smaller size of the major scroll is the answer to start with, but in a factory setting,,that isn't usually going to happen.
So much available engraving room on these Winchester lever patterns is taken up by a wide simple border around the frame sides. That taken out or at least taken down to a more simple line border would leave lots of room to develope the pattern.
But that takes more time to do and that's not what the factory people were after even then.
So when you compare left and right, you don't see the same scrolls,,you don't see the same pattern. It can appear that it's done by different engravers.
You can get away with this if done on a top and or bottom surfaces usually. It's not noticable as 'different'. It has a nice contrast actually. But when the sides are done differently,,it can show up as somewhat odd looking.
There are subtle hints in the cutting that tell that the same engraver cut it.
But it is a problem that you have to or should consider before you start carving it up. It's simply layout.
In a factory setting w/set patterns and timelimits, it's a different story. The thinking, layout and drawing is already done for you. Just cut.
