I speak to Stuart Anderson-Wheeler about once or twice per year. Last time about a year ago (?) there was supposed to be some news out in 2017. Haven't heard it come out officially. A change in the company. The handgun was planned still then and in the "works". Will drop him a line.

A couple were ordered by a member here.

The Anderson-Wheeler Mk VII were being made in .357 Magnum.
