Default 1972 D12-3. Should I fly it?

I'm thinking of flying a junk rocket with a D12-3 made in April 1972 at our club launch this Saturday.

What say you? Should I do it? What do you think will happen if I do?

This D12-3 has been in my possession since it was first purchased at a hobby store. There was a time in the 80's that it spent two or three years in the attic, but since then it has been in a fairly constant normal indoor environment. My theory is that thermal-cycled motors can return to stability over long periods of time.
