Hello,
thanks for kindly comments.
The mud is maked from still water (Vallejo) and cotton wool. After drying, painted dark brown colors and varnished with gloss varnish.
About the pin of the horse, there is no problem. It is strong enough. What Carl said, under normal transport.
The splash is only for decoration and not to firming the hose leg.
Now preparing the duo of the Waterloo clash...
