Tony,
Just my closet OCD kicking in, but looks like HK S_P 89. Perhaps they couldn't find the larger font stamps for the 'SP' to match the size of the HK & 89; the S P looks as if they were stamped afterwards. Are all the early IK SP89s this way? If one were to nitpick a bit more, the H is also different. Damn OCD!
Regardless, it's ripe for a proper MP5K / MP5K-N conversion...
