Boy do we have a motor for you. Actually we have two of these, one grey and one black. These we picked up[ from McDonnell Douglas Aerospace. They were on a surplus list. They have been rebuilt and were on the shelf as replacements. They can be yours if the price is right. Just make us an offer. Here are the specifications:
