This Lionel AB Santa Fe F3 set is from the original owner. It has been tested and works well. The horn is original and functions properly as well. The B unit had one coupler replaced, but the odd thing is, there are no stripes on either side. The original owner said that is the way it was like this when he opened it up brand new in the 50s. Overall, the paint is a little rough with scratches and rub from use over the years. Please look at all of the pictures as they are part of the description and will show you the condition. The battery box is clean with no rust. The power unit box is in excellent condition, as you can also see in the pictures. Unfortunately, there is no B unit box. Please feel free to ask any questions you may have or for additional pictures. We will always combine shipping costs for multiple orders, and we will ship within 24 hours of payment
