what do I have?
 

Just got an old Murray lawn tractor for our church,, in great shape. It's a
10hp Tecumseh powered, 30" deck. Couldn't find any model # on it.

Engine is Tecumseh TBXL220157231A.

Anyone know the likely year and model Murray this is?

Also, I'd appreciate knowledge of any online club or group that deals with
Murrays.
