Any ex-artillery guys here know how to use this?

I am not artillery by trade, but that looks like a table for calculating elevation of the gun based on the number of charge bags of propellant and distance to target.
This slide rule is intended for use with a particular site unit that would be used with the gun. It looks like the process is explained in military speak, and would probably be much more intuitive to understand if you were also looking at the site unit.

Is there a date on the items ?
My regiment had 105mm and we used range tables to calculate elevation for different ranges and the number of charge bags.
The semi fixed ammunition had 7 charge bags and we did most of our shoots at charge 5, that means charge bags 1, 2, 3, 4, and 5 were used, leaving charge bags 6 and 7 to be burned after the shoot.

It says in the first / top picture that it is for a 155mm Howitzer, so if it's Canadian it would be for the M109 SP Howitzer.
19 years in the Royal Regiment of Canadian Artillery for me. Retired as a captain. M109s, C1, C3, C2, LG1s and M777s during my career.
Firing Tables usually are a big thick book with every charge (and depending on the specific howitzer, charge system) laid out for each of the projectiles that could be used with a weapon system for both high and low angle applications. What does that mean in layman's terms? Lots and lots of pages lol. Basically a pain in the ass to pack around with you. There were several methods to condense them to a more portable format and this is one of them. It covers one specific projectile only (https://en.wikipedia.org/wiki/M107_projectile). Other than that it is just a slide rule presentation of tabled data like any other for charges 3-7 (literally bags filled with propellant) that we would fire and 1,2 and 8 which we never did (1 and 2 were wartime only due to the chances of a sticker, literally a charge low enough where the projectile may not exit the barrel, and 8 was a rare overcharge that was a one piece charge we never used due to expense, barrel life, and lack of ranges long enough to use them in).
I guess I didn't answer the question hahahaha. Yes, I could theoretically use it and I could certainly teach you MAPS (Manual Artillery Plotting Systems - IE solving the indirect fire problem without the use of a computer with IFCCS) but I'm sure no one has enough time or interest for that lol. It is a cool piece of artillery data and memorabilia for sure.

Thank you. Only 428 pages. Good bathroom reading material.
It is all necessary in order for the King to put the balls where the Queen needs/wants them.

Us cannon cockers take are duties as King of Battle (Field Artillery) to the Queen of Battle (Infantry) very seriously!
Beside, "Artillery adds dignity to what would otherwise be a vulgar brawl." (Frederick II of Prussia)
God. Remember these. Genetic ammo table for the M107 round combined with the gun book (M109 or M109A4+ or M114 towed howitzer) you can shoot artillery without a computer. The idea was to shoot and record data at as many variables of elevation, range and weather as possible and record it all In ammo slide rules and gun books. Thus in theory evey situation you find yourself in has a solution by combining the book and slide rule, from there you could get the round close to target and resolve the solution with FOO adjustment. In 1941 this was the height of artillery technology and a huge improvement over the German/ Soviet method shooting in every target thus saving ammo.
