One more supplement:
According to a Polish article from 2011: in 1932 (or a bit later) 8 Renault FT were rearmed with 13.2mm MG(!) and assigned to Gendarmerie, being last tanks of this type, and were withdrawn in 1938. I can't verify it elsewhere.
In 1932 Belgium bought 6 Carden-Loyd Mk.VI tankettes, that can be added for a short period.
By 1934 all 6 tankettes were converted to experimental tank destroyers, and were in service by the time of the German invasion (see
http://www.tanks-encyclopedia.com/ww...elgian_T13.php and
http://www.wardrawings.be/WW2/Files/...k6-47mmFRC.htm with photos)
There are no detailed specifications given, but Polish #702 TK-SD can serve as a pattern, with 2-men crew and possibly reduced rate of fire (due to smaller crew and unstable chassis after shots)

I'm not sure if classifying unit 206 76mm Mortars as a mortar is proper - it was an infantry support gun, able to fire directly or with a high elevation -
