Another 66 story.
I took mine apart, had problems getting it back together.
Borrowed this bud's 66, promised him I would just take the receiver cover off to see how the parts fit.
With that one as a guide, I reassembled mine.
BTW, don't take one apart unless you're pretty handy with such things.
I told my gunsmith what I had done. He was most impressed and complimentary that I was able to put it back together, even with the other gun as a guide.
He told me, he gets them in a bag to reassemble from time to time.
Interesting design. Maybe a bit too interesting if you're putting one back together.
