I live near a museum that lets you handle the exhibits, not arms but but everything else. Unless you count an aircraft turret complete with machine guns that you can sit in. The museum started life at Boulton Paul Aircraft Co. It is now called Tettenhall Transport museum housed in the old engine shed at Tettenhall station. Well worth a visit especially if you have children. Large model train layout, motor cycles, bikes etc. Home guard memorabilia, stationary engines etc. It is run by volunteers and open weekends. The staff are collecting anything made locally and have a good selection of locally made objects.
