Hi Michael, the height is a good match for the Jan Beranek. I can't really read the Emanuel Beranek height. I don't see the colourway much before 1953. Most pre 53 designs I have are topas. Also I have seen a few of these and the handmade shaping seems to vary a lot. I attach a picture of one I have. The CGR photo does not show the vase very clearly but the tooling between the 3 lobes can be very pronounced. I have seen examples where the lobes reach the bottom of the vase, as in CGR and give the vase a distinct pear shape. (Also the Jan Beranek pattern drawing is quite poor). Finding this vase in several colourways, as I have done (elsewhere too) suggests to me, a mid fifties approach to production rather than earlier, simpler times.
