Vintage case on Ebay

Just saw this case on Ebay , these cases seem to be rare,I hardly see them for sale. The last one I saw sold for around 400 . I really like the look of these vintage cases, I wish someone would reproduce them. The part where the headstock goes is only about 3 inches wide and will fit only friction tuners , the case is only a little bigger than the uke.
Does anyone know when they stopped making this style case ?http://http://www.ebay.com/itm/Vintage-1930s-Original-Martin-Sopramo-Ukulele-Case-/251355727100?pt=LH_DefaultDomain_0&hash=item3a85f804fc

nice! I'd like to have that for my style O!
