Looks like a 200 that has had a thermometer added to it. Nice grates and overall decent condition. I really enjoy cooking on my Q so much that I used some Christmas $ to buy a 3200 someone was unloading cheap on OfferUp. The 200 will still be my take it anywhere grill. I love cooking on it, but I agree that it isn't suited to a whole uncut chicken. The 300/3200 is taller and larger, so it probably could do at least a moderate sized one. On the other hand, you miss out on the portability. Spatchcock, as Larry recommends, is the way to go! Enjoy cooking.
If you are missing the fold-out side tables, you might keep your eyes peeled for a donor grill with other issues that you can use to salvage these and other replacement parts.
