I inherited this EM RED CROSS dagger and would like to get it complete. can anyone advise on getting original grips and pommel ?

A replacement pommel is going to be hard to find. If you do, the hilt is made of white metal and will be hard to solder together and get a decent job. I've seen quite a few broken hewers over the years and only one decently repaired.

what is the XB marking? is this signifigant?

Could be the owner's initials. That would make it an interesting collection piece. It's a shame the pommel is broken off. It looks in decent shape otherwise.

The only hope you have for this is to find a red cross hewer with a broken oval cross guard, and somehow cannibalize the 2 together. The engraved initials are probably from the original owner, and do add value and interest to hewer. Good luck with your project!

In 55 plus years in this hobby, I have never sent an incomplete DRK Hewer hilt offered for sale. Also, NO crossguards for the Red Cross Daggers were found as left overs in Germany after the war and I know several who looked.
An uphill impossible journey IMO.,

i appreciate your advice. i was hoping for a "do-able" fix. i'll keep this dagger as is then. don't want to get into anything that will cause more issues. thanks guys

I had read somewhere that each dagger part was made to fit the dagger it was put on. IMO I would leave it as it is. It keeps its original history in this way.

I agree with mr bullets completely

There was a hilt advertised recently on eBay. Could still be there. As noted, a very difficult repair, even with the proper parts.
