Pair of controlled bubble glass vases

" />I have bought a lovely heavy of Glass Vases , seem to be real quality but do not have a clue at present to manufacture, any one any thoughts .

Reminds me of Carl Erickson's controlled bubble glass paperweights, but could be Murano

I am not sure why but they just dont seem rite for Murano thay have a verry simple concaved base pollished.and weigh dead on 1 kilo each .

Got it .

 Spijkerbol Vase by Andres Dirk Copier 1936, high Deco who would have guessed i had them down as Scandinavian but late 50's, and to think i nearly walked away from the at £4, i even said to the seller i should not be so tight after handing the money over and telling me her partner had bought them at auction some years ago but i dont normally listen to the rubbish that booters spout , but she seemed genuine , any way happy days.
