Identifying Lino matrices, monotype fonts

All:
I have a minor but size able problem. I have 100+ intertype magazines of matrices to identify and only 28 are labeled. We have found an on line resource for identifying the Merganthaler matrices but the remainder, so far, are identified by the font size and a 4 digit number, so 6 pt. 1234. If someone can help me with the manufacturer I can perhaps find the font style.
And how do I determine which magazines are intertype and which are Linotype? I’m going to assume the differences are somewhat obvious but I was unaware there was a difference until an hour ago.
Finally, the monotype. We have quite a lot of monotype…ah, brass letter molds in holders. Most are marked with reference numbers as well, for example, 10/420. Is there a reference that will tell me what the different fonts are as well?
So much stuff, so little knowledge! Help!

All linotype mags have a saber-like rod running thru the mats. If you pull the rod out all the mats will fall out if mag is not seated on the machine.There are no rods on Intertype mags,

All linotype mags have a saber-like rod running thru the mats. If you pull the rod out all the mats will fall out if mag is not seated on the machine.There are no rods on Intertype mags. If you can find an Intertype font book all sizes and names will be displayed therein.

For your Monotype mats, the book “American Metal Typefaces of the Twentieth Century” has a listing of American mats by number.

This excellent website will provide downloadable info on Linotype and Intertype mats, including matrix list booklets:

In the case of US Linotype mats the first numbers are point size, followed by triangle, then font number, all as one unit. Intertype mats generally have point size, then font number below.
Note that not all Linotype magazines have a removable sword. Many have a built-in retaining system, but if not shifted to the left in locked position, will just as easily drop mats. And it only takes one mat out of position to prevent locking.
Linotype magazines have a cover that pivots and folds behind for use, where Intertype magazines have a cover that is attached on a couple slats and just slides out of the way in use. And Intertype magazines have built-in escapements, so there will be 92 tiny fingers down behind at the narrow end.
