As promised, I have made a batch of seven "Schwere Abschleppstangen", Heavy Tow Bars, nominally for the Bergepanther, but also used with the Famo 18t Recovery Halftrack. Hence the inclusion of all three coupling types.
Five sets have been pre-sold to customers (

The set is all metal, mostly mild steel. The articulated clevis is a custom Dural casting. The retaining pins are brass with stainless steel chains and jump rings. All sets have been grit blasted, etch primed and are supplied in red oxide primer.
Three pages of notes, references and photographs are included as no examples survive in Museums.
PM me if interested.
regards
Fabrice
