I had a Parker BP with a gold or gold plated top and clip and a plastic barrel, and I think the tip of the barrel was gold.
It took a Jotter refill.
The point was activated by moving the top part of the pen.
I thought it was the BP verison of the 51. True? Anyone have any ideas or pics?
Thank you.

Hard to say without a pic, but definitely sounds like it could be a 51 Jotter or 61 Jotter. A Google search of "Parker 51 Jotter" and "Parker 61 Jotter" should show several pics. If I wasn't on a PDA, I'd cut and paste a link or two. Both were cap actuated.
