I have no experience with AyA, so no comment. However, I would like to add some to the following comment.
"Well, save those VERY few that truly do make only Best guns."
Boss claimed "best guns only." Their less-than-best were branded with their shop manager's name, John Roberts, I believe. With the foregoing possible exception, all other makers supplied whatever the customer was willing to pay for. Few makers had all the talent needed for a best gun within their in-workers at any one time. Most of the time some of the work was done by contract out-workers. The men capable of best work were well known within the trade. Any brand could get out a best work gun via the trade. The trick was getting the order. It should be no surprise to to find an obscure brand on a best work gun. Value due to brand? Brand Value 1 (BV1) @ $8X, BV2 @ $6X, BV3 @ $4X, BV4 @ $2X, and BV5 @ $1X; the foregoing for five guns of equal original quality work and in the same current condition.
