Hallicrafter 509 image shifted horizontally

[ohohyodafarted]

Just finished recap of a Hallicrafter 509 10". I have good vert and horizontal width and locking. I have good vertical height and locking. However as can be seen in the photo attached, the image is shifted by 50% horizontally. I assume the vertical bar up the center of the screen is the horizontal blanking interval that would normally be at the right side of the crt and out of sight off the face of the crt. Because I have full height and width I believe the horizontal and vertical of the deflection yoke is working so I do not suspect the yoke itself.

In the attached photo (although it is hard to see the detail of the image) the half of the image on the right side of the vertical bar is actually the left half of the full video image. (IE: the image is shifted to the left by 1/2 of the screen)

I am not real good at tv theory so I am hoping someone with a better technical background can point me in the right direction.

Thanks for your help!
