Hi all,

Another Model 10-10 marking question. I assume this is a 1988 series gun (it's marked 10-10 model)

This one has a nice "CDC" mark on the frame, assuming that means California Dept of Corrections, looks like all the other ones I've seen.

On the other side, electrostenciled not so nicely is "IWSP R0087" or some such.
Any idea what that means?
