Tango glass vase with tadpoles - Loebl

This is starting to be a very familiar shape for me - 6 feet with ribs. In this case, the clear cased yellow tango glass has been mould-blown then the tadpoles applied, I think.
The Loebl hallmark is - possibly - in evidence - but this isn't helpful in identifying the maker, I think - but if I am wrong, I would be delighted.
I think I am starting to think that the company were importing some interesting glass but not necessarily from one company.
The date for the silver (assumed to be contemporaneous with the glass) is [k] for 1925, although I find this difficult to differentiate from [h] for 1923.
This is one with Vetraio's input specifically in mind! :-) He has form!
