INTRODUCTION

Clarification

Whilst it has been possible to identify nine versions of the stove it has been impossible to clearly identify when all of the versions started or finished.

A stove has been classified as a version when the normally fixed parts have changed. These parts include the pump knob because that is not removed from the stove during normal dismantling. Parts like reserve lids and burner plates are loose, easily lost and readily replaced so it is difficult to say that they are part of the original stove. Whilst these help identify the version the fixed items on the stove are more reliable for identification.

Definitions

? following a year means that there is evidence that the version existed in that year but it is not known whether the version existed before the first year or after the last year. eg 1926?-1931? means that evidence exists to show the version existed in 1926 and was still in existence in 1931 but the version could have started prior to 1926 and continued after 1931.
