Can anyone ID this S&W Model 29 ?

Can anyone help me ID this S&W Model 29 ? I just got from a buddy of mine at a price to low to refuse but I'm not S&W savvy enough to make heads or tails of these markings under the grips.
Attached are pics-left, right and bottom- anyone have any ideas ?

It doesn't look like the barrel is pinned, so probably a later version. What would really help is a couple of close-ups of the numbering on the cylinder hinge (crane). Release the cylinder all the way open, shoot a couple of pics of the markings at the base of the hinge where it meets the frame.

made in July of 1985 that would make it a 29-3, grips are correct for the time period, should make a good shooter.

Here's my list of changes for that model. It's from a little while back, so there may be more up-to-date info, and the folks at SWforum could say for sure, as f4tweet suggested.
