That D261 is the date that the block was cast. It reads as:
D= April
26= 26th of month (April in this case)
1= year '61

It's a coincidence that it happens to read "261," and a confusing one!
As far as I know, the rods would look the same, but I'm not sure if they would be longer from 235-261. Hope this helps.
