I have been on the quest for a Mexican Oliver for some time. They are nearly impossible to find here in the US. What makes a Mexican Oliver special? Well, I have found some pictures from Mercado Libre to give you and idea:
A Mexican Oliver is nickle plated on the bottom while still retaining the green paper table and front piece. I can glean no information about why the two-tone Oliver was so popular, but it's all you find in Mexico.
For a long while I felt as if I would never get a lead. Mercado Libra frequently has them for sale, but my inexperience with the language and fear of buying something so expensive so far away makes it prohibitive. I can't take a vacation to go look for one because there 32 states and one federal district and they could be hidden anywhere. But now there is a slight hope.
Andres, one of my students, has an uncle who is a journalist with a newspaper in Mexico City. He's spotty on the details because they have never met, but this summer he is taking a vacation to visit him. It was kind of Andres to offer to ask if he knew the location of one and I am sure that a journalist would know just the right people to contact.
So, this little quest is taking on a new dimension, but it's still exciting.
