The weight has a spatter base that is typical of Begium weights.
The crossed flags would seem to indicate an alliance of some sort. The black yellow and red flag is the Belgium flag but as for the black white and red I have drawn a blank.
Its not the french flag as this is red white and blue and has been since 1790. The Belgium flag is said to be based on the French tricolour and was adopted in 1831.
One of the German flags from the 1860's through to 1935 was black white and red stripes but the stripes were horizontal.
Any one else have any ideas on what the black white and red flag could represent??
