Given the condition of the paint and stencils, $40. Of course it depends on where you are and who is selling it. Machines like that in antique shops are typically over $100, but that's because they would have bought it for $40 or less.

What makes this a less desirable model, and make it available for little money, is that extra wide carriage. I've only been buying standards of late, they're my new best friends, and they're often cheaper than portables. but wide carriages are still a turn off for me and most other buyers as well. I don't have any practical use for them and they take up so much room (and add a lot of weight).

Good luck and let us know if you end up with it!

The Royal 10 is an icon, but there are plenty around and that one looks like it's seen better days. At least it has the original spools. Most old Royal machines that I've bought didn't and the ribbon reverse mechanism won't work properly without them. I'd offer $30 to $50 depending on its mechanical condition and the assumption that all the beveled glass panels are there and in one piece.

Uwe, thanks for all the help. One other question. What would the value be for an Underwood No 5 that looks to be in great condition?

Thanks.

Thanks for the very detailed explanation. 

Craigslist is a good source, but I also keep an eye on eBay and Kijiji. With repsect to eBay, it's normally a cost prohibitive source if you want to buy inexpensive machines because of shipping. However, you can search for eBay auctions that are local to you and then arrange (beforehand) with the seller to pick it up instead. Antique shops are usually not good places to look because they're trying to profit off a machine that they paid what you would have for it, but on rare occasions bargains can be found if you find the right store owner. I've bought a few really good machines from such stores, but it's really low odds, so I generally don't bother with them. Thrift shops can be a good source too. Again, they are very hit and miss depending on where you live.
