JOK — I think it could well be Walsh. That squashed stem (I don't know the proper name for it)
* is a known Walsh feature, dating from the late 1920s at the earliest. In fact I believe it could well be one of the innovations introduced by Clyne Farquharson soon after he joined Walsh in the early 1930s, when you see a number of improvements made to existing ranges to bring them up to date. The stem is known on marked Walsh pieces — on both plain glass and glass decorated by engraving, such as the waterlily and iris vase shown on p.38 of Leibe,
Miller's Glass of the '20s & '30s, 1999. Other examples are shown in Reynolds in plates 21, 27 and 38.
Please would you let me know the colour of the glass of the stem. Some Walsh examples, such as the one shown in the Miller's book, have the stem in a different colour to the main body and foot.

* I am reluctant to use "knop" or "rudimentary stem" as these terms already have quite specific meanings in other glass fields.
