Kensington window parts

Your pivot shoe looks like a dead ringer for our 15-177, but I'm less certain about the pivot bar. Look at our 26-466 to start out and see how well our dimensions line up to yours. If they differ significantly, tell me how. I'm mostly concerned about hole placement, overall length isn't that important. 

Unfortunately, I have no reference for that code in my records, so I'm not sure exactly what it is you're looking for. Before I make a recommendation, would it be possible to see a few photos of the part in question? I can then check our inventory for a match. Thank you!
