I don't think I've ever seen a little Morse. All the ones I have seen were really heavy standard size machines.
To be quite honest, I don't think it's worth a lot of money. Many people don't like the older heavier machines. Although they were the "portable" of the time, they weigh a ton. If you carry one, you never want to rely solely on the carrying handle; always support from below.
They are a solid all-mechanical vintage machine, and tend to be workhorses. However, they are not in great demand, probably because of their weight.
