The smallest (3rd) Vennbahn enclave is 1.65ha, 16500square metres, or equal 
to a sqaure 130m on a side. It is thus over 10 times larger than the 
smallest Indian enclave for which we have data.
It is not quite rectangular, but about 100m N-S and 150m E-W.
I measured it using a planimeter, so it is measured off the map.
Also attached are 1973 and 1983 municipal maps of Belgium, cropped to the 
enclave area. The 1983 map shows the Germanophone region by the dots along 
the municipal boundaries.
The 1973 map has dates penciled in by me along some boundaries, showing 
where the Belg-German boundary was at several time periods.
The two maps show the situation before and after Belgian municipal 
roorganisations. I also have a 1990s map, but there is no difference in the 
Vennbahn region.
