Saltzman enlarger frame opening size

[Jim C.]

I've been cobbling parts together to build a horizontal 8x10 enlarger around a
Saltzman Neg carrier that I have, I'm curious as to how big the opening is
on the light source side is. My best guess reverse engineering off of pictures of a
Saltzman horizontal enlarger is 11.5" X 12".
Can anyone that owns a Saltzman confirm my measurement or provide what theirs measures ?

Attached picture is looking towards the lens from the light source side, the red square
is the measurement I'm looking for.

Anyone ?

With mine the rotating negative carriers is strictly 8"x10". There might be others.
The light source size is about 14" for the condenser version.
Can't help with other configs.

Jac,
Thanks for responding, the neg carrier I have is also an 8x10, from what i can tell from catalogs
their horizontal enlargers is just the one model of their enlarger head horizontal on rails.
The condenser may be 14 in diameter but the aperture that lets the light thru to the negative holder
couldn't be 14" square.

[...] The condenser may be 14 in diameter but the aperture that lets the light thru to the negative holder couldn't be 14" square.

The diameter of the condenser is 14". The square that fits into 14" circle is 9.9", which covers the actual exposed area of an 8x10" negative. (The negative size minus the area covered by film holder.)
