The last good number I had for Mr. Romo was 713 305-8540. I spoke to him on that number last spring. I just called the number and a non english speaking person answered the phone( sounded like spanish) and it seemed like thier home number. It definately was not AIMCO.
Hopefully Mr Romo just changed phone numbers and is not out of business.
My Mitchell luger had a roll pin for the Extractor pin.
Hope this helps,
Chris
