No, mine came with the 16" bar.

It's getting to the point that all the chain saws look alike--except Stihl. I have a early 80s Poulan Micro XXV that just won't give up the ghost. If and when it ever does, I'd seriously consider an Echo. I have an Echo string trimmer that's almost as old and still runs good.
36 cc sounds a little low to be running a 16" bar. Keep the chain sharp! If you're seeing sawdust, not chips, coming off of it, you're overdue on sharpening.
Then yours takes the same chain as my CS370. It should be stamped with:
16"
.050"
56DL

Here's a shot I took of mine after cutting a bunch of biscuits from an old white pine. I was tuning the carb and just having some fun.
