The support squadron is EWM and Caesar mostly. The work on the EWM MMG's figures is on the coat in order to make it unbuttoned, and on the puttees in order to turn them into cavalry boots by using filler and painting them black. The horse holders are Caesar figures with Hat standing horses.
The 25mm SA34 AT gun tow was built in Evergreen. The horse is one of those nice Revell German horses of the artillery set pulled by a conversion from Caesar and a Hat driver.
The three mounted cavalry squadrons have plenty of Esci horses as many of the original Hat were used for the horse holders.
The fourth squadron, like in the 11e Cuirassiers, ride their butt-pain bikes due to the lack of horses.
The HQ of the regiment has Hat cavalry figures and Caesar foot. The 60mm mortar is scratch built.
The command stand is the usual Hat figures with the cornet having a Hat Napoleonic British arm instead.
Next: more French 1940 probably, command cars and the last two H-39 for all big units. Also the two cavalry regiments in dismounted positions is a possibility.
