This kit was been introduced to meet modellers' requirements for a smaller frame than the SM1 14-lever kit. Provision has been made for the frame to be a unit of 7 levers in a larger frame, either during building or at a later date. The catch handles are now supplied as two ply, for additional strength in use. An optional improvement is to fit the catch handles to the levers with 10BA screws and nuts, with a washer each side of the lever. It is easier to obtain a fine adjustment this way, to prevent slop on the catch handle. These parts are included in the upgrade kit SM2/1. A new design of catch block and "U" bolt has been introduced to help in making a better job of this item. 3/64" square brass rod has been provided for the catch strips as this has been found to be more positive than the etched version in SM1.

All parts needed to construct the frame shown in the photograph are supplied in the kit.
