I have a Speed Graphic Pacemaker, which due to health reasons I was unable to use for some time.
Whilst attempting to open up, I found the lens mount assembly had become detached from the rails and have since had no success from realigning as I cannot get the `locking flanges` to slide to allow the lens mount etc to rebed on the rails, as the Front Standard Lock appears inoperative. in spite of turning the lever.
I have, in the past, had no problem of a rails disconnection.
Can any one help please?

Hi Fred,

If the problem is just the front standard (the vertical part that holds the lens board etc) that has come loose, center the lock, wind the focus rail right back, grab the front standard and pull it right out (stretching the bellows) and slide the standard onto the rails from the front. The standard can then be moved back to a normal position and hopefully the lock will work again.

Cheers,
Bruce

Hi Bruce,
Many thanks for your advice.
It`s now fixed and I am `back in business`!
Cheers,
