The thing with the Doral model is that they have fender eyelets in the rear
Edit:
I found this bike in google images from a local bike website. They seem very similar including the rear dropouts, squared off stays, components and fork. The photos arent the greatest, but website indicated that this model was
Ishiwata 022 cro-mo quadruple butted tubes (including stays and forks).
hope this helps
