Need help indentifying vintage road bike

I found a vintage road bike in a barn. It is a 26" ten speed with drop handle bars. It is a nice rider in pretty good shape all I needed were two new tires and a clean up to ride. The only name on the frame is Araya on one side. It has a Shimano Eagle rear derailleur, Shimano Thunder Bird GTO front derailleur, Shimano stem shifter and brake handles. There is no serial number to be found on the frame. I am sure the seat is not original and I added the bottle holder. Wheels are also mismatched, front wheel is marked UKAIRIM26X1 3/8WO made in Japan, Rear is marked M.O MFG. CO. Everything works well. Can anyone help identify this bike? Sorry I can't upload pictures new to the forum.
