So this just happened to me.

[FredMnkyDad10]

Trying to do and hold 4 things with only two hands. Fell out of my hands and of course it had to hit the edge. At first I thought it was a pin or screw that I heard. Then I saw the piece. Freaking frak.

big sad ;(

Aw crum! I bet you can fix it with glue, and maybe a small pin.

[Ecapnation]

I've noticed that the resin in these is aging poorly... Had one of my crack worse tightening it on a improperly set sear pin

Drill and pin it. Modellers do it all the time. Should hold quite well since there's no load.

I bet if you take it to a local carpentry shop they'll set you straight for very little. That's what I would do.

Super glue good as new
