I've noticed on quite a few 113's that the front and rear bumperetts are cocked/tilted back... sometimes one, sometime both, sometime unevenly.
Can only assume this is from impact of some kind. I've stood and bounced on mine (ashamed to say), and they appear pretty stout, so it must have been a pretty good wallop to cock them back.
Is this a particularly weak point in the design and use of materials? Why always tipped back at the top and not at the bottom? Is correction simply the proper use of a mallet on the bracket or is it more complicated?
