Is this Loetz?

I love pieces that have a different type of application, shape or finish- this one has it all. It is a 9" Loetz with drip feet and arms with a flash iridescent finish. This was made between the late 20's or early 30's. "Is this loetz?" Are what I remember the dealers first words were. "Yes", came emmediately after with a jump in my chest. The next words were hard to answer... "How much is it worth?". Then silence. The Selena with haggling for pieces are that it seems to be a game- and a Dealer, I'm not. So instead of the "how much do you need to get for it" response, I just quoted a number where I can afford it and if I Sell it I could get my money (or most of it). I think how much you pay is sorta not the point for a collector. My internal question is more like: does it add value to a group of vases?, does it send me in a new direction or does it did go deeper in a vein of what I have. I then set a good price with not much wiggle room; then the reply: "I can get it for you for this price (shipped). It was even better than I quoted and made me realize that an honest offer is always rewarded.

The last pic shows why it was so valuable to me
