Yes, indeed, Jeff---#6 at Bellerive is a par-3, with a front left to back right angled green with a pond along the front and right. The green is 46 yrds from front left to back right--Yikes!
The back tee (as of 2003) was at 195 yds, and the blue tee (next up) was at 171 yds.
Don't know how those compared to 1965, or to last year's Senior Open yardages.
