I could easily scan that and share the file, along with instructions on getting metal sintered (3D printed! ) versions from Shapeways, just like we did with the handle pieces. I'd just need a loaner to scan.... broken is fine.
Tasche (runfastflyfar) sand-casted some emblems a while back, but it was the later style. I may have that early style in a box, I'll take a look.
VHB tape will work, but you need to make sure the surfaces are clean, and you may need to scuff them a bit to give the adhesive a 'tooth' to hold onto and figure out a way to apply some pressure to the emblem for a while.
