Antique Cut Glass Mug or Stein?

This is an old cut glass mug or stein that I purchased a couple of years ago. I posted it awhile back on another site but didn't really find out too much information on it.

It looks like it may have had a lid on it at one time because of the cuts on the upper side parts of the handle. There is also 0.5L etched with a line cut or etched in the glass near the top.

The mug measures about 6 3/4" in height with about a 2 3/4" wide top rim and about a 3 1/2 wide bottom.

Can anyone tell me anything about this mug or stein like when it was made, the glass pattern name, where it may have been made or anything else?

Thanks!

It looks like it might have had a cover at one time.

 

Thanks Davey, I would have to agree. I was thinking pre-ABP earlier than 1880 somewhere in Europe.

Bev, yes, the 2 etched cuts on the upper side of the handle (1 on each side) most likely had perhaps a pewter lid or some other type of metal attached.

 

Agree that the 0.5L would indicate European origin.

The pattern would be considered a "cane" pattern.

 

Though the metric system is known in Europe from 17th century (The story of the metric system starts, somewhat unexpectedly, in 17th Century England, with the proposal by the natural philosopher John Wilkins for a consistently decimal system of units), but it was using much later in Europe... only in 20th century. I mean the sign: "o.5 L" says it is not antique glass... Isn't it?

 

Here's an interesting read from Wikipedia

Ref https://en.wikipedia.org/wiki/Metric_system

"In pre-revolutionary Europe, each state had its own system of units of measure. Some countries, such as Spain and Russia, saw the advantages of harmonising their units of measure with those of their trading partners. However, vested interests who profited from variations in units of measure opposed this. This was particularly prevalent in France where the huge inconsistency in the size of units of measure was one of the causes that, in 1789, led to the outbreak of the French Revolution."

Original metric system
The French law of 18 Germinal, Year III (7 April 1795) defined five units of measure:

• The mètre for length
• The are (100 m2) for area [of land]
• The stère (1 m3) for volume of stacked firewood
• The litre (1 dm3) for volumes of liquid
• The gramme for mass.
