Thanks for letting me share guys - you’re all the best!
Yes, the mixer on the left is the new one (I just couldn’t resist the shiney finish). I purchased it as a refurbished model on the shopkitchenaid.com website, for a great price (thanks Hector).
The mixer on the right is 12 years old and still going strong (my mother’s KA is over 20 years old and still going strong, althought she doesn’t use hers as much as I use mine). I can’t wait to see how well the larger bowl handles a big batch of Mousseline. And Matthew and Hector (oh, and Rose of course) have inspired me to step into the bread baking world, so I’ll eventually do that after I page through The Bread Bible a few more times.
Jeanette - I bet your 1973 Kenwood is a real beauty!!! You know the saying, “they just don’t make them like they used to”.
