Perhaps surprisingly, before hanging up my shingle, and in fact after hanging up my shingle, I was not afforded the opportunity to fondle and inspect (take apart) one of those Belgian Centaurs. I am crushed.
I also haven't had opportunity to get together with the proud recipient of his Knew Two Ewe Belgian Centaurs. Curses .... foiled again (Famous stolen cartoon line). I am working on it though. Last Ohio match, one of the "other" guys walked up with his brandy darn'd Knew Two Him Centaur. Basically unfired. Nice Gun. Main Spring came out of a Mercedes Unimog. Some heavy. I personally wouldn't shoot the gun with that spring in it. Way over-sprung.
