I am aware the prop is like that now, but in that series of pics one is facing the breech rear at an angle you can see the white resin as if it has been broken. Also the only cap that i've found (just b4 Luke cuts it) that shows that area seems to indicate the hammer tail was longer, maybe full length. So broken during/after production? Only my guesses/opinion of course and based on that i made the 'artistic' decision to leave it unmodded.
If you want to shorten it, that's easy with little saw and sanding stick. a touch of matt black and a smear of GW Mournfang Brown and you're set.[ATTACH]222359[/ATTACH]
