Decent replacement arm for an infiltrator from shadowspear?

[chapter master 454]

So back when shadowspear dropped I got a box of it and during the building of the Infiltrators one of their arms went on the most incredible drop bounce I have ever seen and went into the warp. I searched high and low and all around my floor for the arm, I managed to find a long lost centurion head but no boltgun arm. To this day I have denial searches for it, thinking I haven't looked in one place or another. I just want to have the model complete so I am wondering if any fellow frater knows of ether a box or model that may have a spare arm that would work for this infiltrator. It is thankfully one of the posing arms that hold the bolter one handed.

 

If it helps direction, the arm would belong to the one in the shadowspear box that appears to be talking on a radio.

 

Please end this pain...I just want to have a finished model...

It's a slightly different direction, but have you considered/tried bitz sites?

Tried but no luck, hence why I am asking...though doesn't mean I ain't continuing to search and try

You might be able to use an arm from Reivers. A box of 3 ETB Reivers is pretty cheap and might work for you.

Maybe a regular first born marine arm and use some card or GS to make it fit? Or extend it with some paper lips and tube or plastic rods and make it an augmentic or bionic arm!

 

(I feel your pain; lost a FW grav chute the same way and not my Scout Sgt is the only one of the squad missing one; I still ask myself; where could it have gone!??!)

Quick update, I investigated the Infiltrator box and noticed that it did have spare arms (something like 8 pairings with 8 boltguns) so I decided to get a box and just nick the comm specialist arm where he is supposed to be using his computer thing, so now the shadowspear guy has both arms at last.

 

Just thought I would post that to note that the kits aren't as incompatible as first thought in case it helps anyone.
