C19 Cabinet Knob

[BwanaJoe]

Hello,

Fifth dumb C19 newbie question.

My 19 was missing the knob when I rescued it and it was the first part I bought (off Fleabay in this case). It LOOKS like the correct knob (and cleaned up VERY well) but when I went to install it the nubs on the back of the knob did not fit into the circular recess in the door. (Those nubs ended up denting the raised bit under the knob on the door) Just curious if this was from an earlier/later door. Also, what should the back of the knob actually look like?

In the long run I guess it doesn't matter as long as it looks correct from the front but I am curious. Thanks.

It certainly looks like the correct knob from the back. The variance in "nubs" on the back could be a matter of C-250 vs C-19. If it looks like this from the front, I'd just bolt it on and forget about it. Mine is a C-19, incidentally.
