There is a HUGE spread in perceived quality (brand value) between these makers. Many of them didn't even make the guns they sold. SO who should get credit for the guns... the retailer or the actual maker?
I would add A.A. Brown, T. White, Anderson, McKay-Brown as providers of best class guns.
Rocketman's charts can be obtained by PM to Rocketman, if he so chooses to distribute them. He does the work.
Chukarman, your emphasis on "HUGE" suggests you know something that thousands of actual buyers of these guns don't.
Which may be true. I'm not arguing either way. However, Rocketman's charts are based on actual sales data, not speculation. The sales data quantifies a broad selection of opinion. So it's a good measure of how the market values the brand name.
The OP also specifically said pre WWII.
Perhaps this will help those unfamiliar with the charts.
There are three criteria. Original Quality. Current Condition. Brand Value.
Each of these are distinct yet key to our evaluation of a gun and more importantly to those in the market to buy or sell, what the dollar value for a particular gun might be in the marketplace. Very often, people confuse or conflate brand value with original quality.
