Got what I expected!

I ordered a cross that I saw online but initially received something else. After inquiring with Old West Iron they spent time looking up my order and quickly made it right. Impressed with their service and very happy to have received what I ordered.

Hitching Rail

OWI fabricated straps for my hitching rail. I attached the straps using 4" lag screws with heads that matched the strap rivets. They did spectacular work including bending the straps to fit the smaller sized rail. Love their work!!
