Yes, those are the correct models.

When Cub Cadet discontinued the saws, they dumped huge numbers of the 18" and 20" [CC branded K095] bars for the 5720 onto dealers to closeout. They would show up on ebay for really cheap money. Those seem to have dried up and now everyone is pricing them above what they are worth.
We just drag them down..... Until they're just like us !!!  BNL

Went through the 156 and its good to go. Runs and cuts as it should.
Figured out why I couldnt get 152 started. When check seen it had wet plug and spark. So puled muffler even though had compression. Started to score and least 1 ring stuck for sure. So will be digging deeper in the 152.
Only bought the 152 for a bonus when buying the 156 from owner. 156 was the one I wanted. Like how the 152 is built and not a clamshell for a homeowner saw. 156 pro style imo, mag case etc.

50 52 seems to be 45mm bore   50082014a piston kit
ring 50080013r

57  56 seems to be 46mm bore


using the bore and figuring cc claimed that would make the 50 52 32.5mm stroke and the 56 57 34mm stroke
