Database of Metal Constructions Systems

Alongside his Other Systems Newsletter (OSN) Tony Knowles has produced a database of all known Metal Constructional Systems and their most important parameters. By his kind permission, his database is now also available on this website. You can search this database using a number of different parameters as shown below. Note that more than one parameter can be selected at the same time.

Note that the bug which prevented results being displayed when a date range was selected has now been fixed.

Boy with Gantry Crane model in logo (or ad?). It appears to be a framework but material unknown. It may be wood because what could be a hammer is shown in the illustration. 1913 mentioned.

Ebay set has electrical parts on lid & more or less conventional parts in box, so are latter all original? Parts include Strips, Angle Girders, 5x11h Flanged Plate, 4x4h & 10x10h Plates with centre hole & 4 holes around it.
