Huge and Heavy Deco Pink Glass Flower Frog - Walther?

Very large Art Deco pink glass flower frog.  The colour in the photographs is far more orange than reality.  The frog is more of a salmon pink.  I have trawled through the catalogues of numerous European manufacturers and have found an almost identical frog in Walther's 1937 catalogue.  The Walther frog is smaller, being  8.6cms.  The frog in this listing is 12.5cms.  I am fairly sure that it is a Walther piece.  The frog has a series of 6 rectangular feet at the base.  The frog is slightly out turned and has a wide upper lip.  This lip is also raised at the top of the frog, which leaves a large central recess into which the flower holes are placed.  There are 19 flower holes.  There is also a recess (deeper than the feet) on the underside base of the frog.  The frog is in great order having no damage.  There are the usual manufacturing issues of roughness round the  base of the flower holes and one of the feet has some roughness on the outside base (caused when the foot was ground at the base - same sort of manufacturing issue as the grinding of the flower holes).    The frog measures 12.5cms across the upper rim and is 9.5cms at the base.  It stands 4cms tall and weighs just over 500gms unpackaged.  Postage throughout Australia will be $8.  Please note, I always try to post the next day after payment is received (post office hours permitting). I accept Paypal, direct deposit and post office money orders only. I do not permit pick ups by local bidders.
