This one looks more like AVeM to me than the Chinese pieces.
Most of your AVeM tutti fruttis will have smoothly polished bases. I've seen one exception -- a vase that was made for KB. The base was slightly frosty looking, instead of being finished to the final high gloss. It was not matte as many Chinese and US pieces are. It was just not as well finished as I would expect for AVeM. It had the KB and a generic Murano sticker. I think it was AVeM. Maybe they were just in a hurry with a large order so didn't take the base to the final stage?? I attached a picture of the vase. The flash was used to bring out the slight matte finish of the base -- it was barely visible under normal light.
