You're a super cool baker if you're using a KitchenAid Hobart Model K5-A (before they used serial numbers!). This puppy is about 50 years old, and is in beautiful shape with the original mixer, whisk, dough hook, a small bowl, and a large bowl.
Look at her shine! She's hot stuff for an old lady, and likes to show off by spinning in circles at TEN different speeds. I think I'll buy her some red sparkly high heels.
If you have any details for me about this mixer, especially the actual date of manufacture, please leave it in my comments.
