That had occurred to me, but I only have access to basic hand tools which would make it quite time consuming. I may feel more enthusiastic if I find a suitable piece of metal tube that has the correct dimensions to fit the tang hole and the bolt width.
A placeholder fix I am considering is joining the tang and the crossguard together with small dollops of epoxy under the grips. It should secure the crossguard, but be reversible should I ever find or make the missing parts.
PS. Why did I buy it? It was because I found a very reasonably priced Vietnam era M8A1 scabbard in an army surplus shop in Bremen, Germanywhilst on holiday there in July and was looking for something to fill it.
The other option was a repro M3 knife.
