Thanks for your comments folks

The base is very gritty and impossible to see if there would be any marks at all. Nice to see a similar pair John - thanks for the link. May be they only marked the ones with smooth bases

I have a thing for orange glass

so just had to have it, even though my orange 'collection' is c.1960s, but I did think at the time, before getting my hands on it, that it might be Welz or some other Czech company and not 1960s as suggested. Its quite slimline and just over 6 inches (16cm) high and 2" (5cm) at its widest. Weird but strangely wonderful.
