Resident in New Zealand this simple though charming plain-turning lathe would have been made circa 1900 to 1920 - though a later date would not be impossible. Of unknown origin, the lathe has bed feet of a distinctive shape - and in a style not seen before by the writer, a fact that hints at the possibility of a previously unknown manufacturer (though certain elements are not unlike the English Holmes).
With around 12 inches (300 mm) between centres and a 3-inch (76 mm) centre height it was of light construction - though the headstock had two spindle bearings with the drive pulley between them and not the expected single front with the rear supported against a hardened centre - a rather common fitting on this class of machine from the mid 1800s until the late 1930s. The lathe would originally have had a headstock pulley with narrow V-grooves to take a round leather belt - the fitting shown is a modern replacement.
With a flat top and 90° edges the bed had a central slot that aligned headstock, slide rest and tailstock -  the latter unable to be set over for turning tapers and carrying a spindle that passed clear through the threaded handwheel.
Although the top and cross slides were bereft of micrometer dials their feed screws were arranged to extend outwards by a few inches, this arrangement allowing the slides a useful amount of extra travel. Converted to take a Z-section V belt, the headstock would originally have mounted either a 3 or 4 step pulley to take round leather belt or a 3-step flat belt drive..
Should any reader own a Wren lathe, the writer would be interested to hear from you.
