Pewtered black glass globe marked "Tchecoslovaquie"

My usual founts of all knowledge are a bit quiet on this - even Miroslav Becka http://www.miloslavbecka.cz/skla/ - which is unusual, for the size and breadth of this collection.
So, a black glass globe with pewter wild roses.
It has the French/Belgian linear acid stamp at the base that has been linked with Kralik...
Can someone help? The last of this month's purchases. (Famous last words!).
It is 15.5cm in diameter, 13.5cm high and 9.1cm across the rim.
