I came up with a few things.
# Concealment Ratings and Rules
1 pistol/revolver under 12 cm (5") barrel length and 680 g (1.5 lbs)
clip for autoloading pistol, sheaf of darts
2 pistol/revolver under 15 cm (6") barrel length and 1.1 kg (2.43 lbs)
clip or magazine for rifle or smg, pouch: 10 stones
3 anything under 38 cm (1'3") overall length (stock folded) and 3 kg (6.6 lbs)
quiver/case of arrows/bolts, blackpowder kit and pounch: 10 balls
4 anything under 76 cm (2'6") overall length (stock folded) and 4 kg (13.2 lbs)
chaingun ammo belt, shoulder rocket/missile
5 anything under 120 cm (4'0") overall length (stock folded) and 11 kg (25 lbs)
combustible accelerant tank (for flamethrower)
6 anything bigger than 5
Determining Concealment/Detection (summarized from core rules)
1 Add Concealment Rating of all weapons, clips, etc. together for a Total Con.
2 Standard Diff to casually spot concealed weapons is 10, 6 if looking for them
3 Add foe's Perception Attribute to your Total Con. to get his AV
4 If AV + dice roll Action Check meets or exceeds 6/10, weapons are spotted
Lifting and Throwing
The rules say you must make a Str check against a difficulty to lift things, such as:
Diff Kilograms Lbs USD Example
1/-0 6 – 11 13 - 24 tire, karaoke machine, very large cat
2/-1 12 - 29 25 - 64 wooden chair, child, kayak, gold ingot
3/-2 30 – 41 65 - 91 large dog, TV, wooden table
4/-3 42 – 53 92 - 117 bookshelf/parking meter/barbell
5/-4 54 – 67 118 - 148 Average HK Adult
6/-5 68 – 82 149 - 181 Athletic Adult Male
7/-6 83 – 99 182 - 218 Lg Adult Male
8/-7 100 – 118 219 - 260 V. Lg Adult Male

15 451 - 825 991 - 1815 Polar Bear, Average Adult Horse
16 826 - 1125 1816 - 2475 Compact Car, Great White shark
To lift, using an example from the book, an "average person", which they list at 60kg (135 lbs, bit light in my opinion), it is Diff 5. I reflect this lightweight "average person" as an Average Honk Kong Adult, as most Western males will exceed this, and list them separately,though I know the point of FS is to avoid charts and tables and extra rules, these are just my house rules and I'm just putting them out there to get thoughts on them and offer them to others for use if they feel they might be handy.
As stated in the core rules, If a PC's Str exceeds object's Diff (determined by weight/bulk etc) by 2+, a Str Check automatically succeeds.
Normally, to throw an object not weighing a whole lot and not terribly unwieldly, you simply make a Martial Arts check, possibly adjusted by modifiers if you're throwing the object at a certain distance or size of target, and always modified by the size/bulk of the item being thrown. I'm setting the standard "easy" (-1) thrown item at less than 6kg/13 lbs (this is like throwing a full bag of potatoes you buy at the grocery store); pretty heavy but they ARE action heroes, plus I'm presuming the throw is only five feet or so, and at a person, requiring no adjustments for distance or small target.
For objects whose weights the PC's Str does not exceed by 2 or more (in other words, 7 Diff or less for Str 5 PCs), the PC will have to make Str checks AND Martial Arts checks to throw the object. The core rules have further examples. which I reflect in my chart above (TV set or wooden table is thrown at -2 etc).
Now, to throw an object listed in the Lifting chart, the book says to double the Diff, so to throw a 60kg person, it is Diff 10. Notice the 5/-4 on the chart above for Average HK Adult - you'd use the 10 and double it, rather than use the -4, that would be for some other modifier related to lifting, probably a half lift or something that didn't involve bodily throwing a whole person around.
My formula for throwing is: a character can throw an object a max distance in yards (meters) = (Str -2) x20 / Object's Weight in Pounds [Kg x2.2 to convert], with 1 yard or meter = 3 feet.
So if you have Str 5, you subtract 2 from it to get 3, multiply that by 20 to get 60, and divide it by the object to be thrown's weight, say 10 lbs (the aforementioned bag of potatoes), which is 60 / 10 = 6, giving us 6 yards/meters, or 18 feet. A Str 5 PC can throw 10 lbs 18 feet. While that may seem high, I have actually done some actual internet statistical research on this and it seems to come out right - this would be the upper limit for an average person, but they could do it, though maybe not consistently. This also would allow for throwing that aforementioned 60kg HK male, say 150 lbs - this would result in .4 meters, or 1.2 feet, which is about right, you could lift someone and could throw them down to hurt them, but it wouldn't be very far, without you yourself moving. I'd presume your movement would have some penalty while carrying someone etc.
Movement and Speed
Difficulty Modifiers: Speed (Using Guns, etc.)
Diff Mov Kph Mph Examples
1/-0 1 3 2 stroll
3/-2 2 7 4.5 walk
5/-4 4 15 9.5 jog
7/-6 8 25 16 human sprint
9/-8 12 50 31.5 fast animal, average racehorse, avg train
10/-9 18 70 43.5 car in city, record 100m sprint
11 25 90 56 cruising car, cheetah, train on open track
12 36 130 81 human powered vehicle land speed record
13 50 180 112 fast car, expertly thrown weapon
14 90 320 199 falcon diving, typical bullet train, arrow
15 100 350 218 race car, typical tornado, x-bow bolt
16 150 525 327 top dragster, fastest train, rifle bullet
Formula to determine KPH from Move = Move x 3.5, rounded up to nearest 5 [Kph x 0.6137 for Mph]
I also have a chart for damage based on speed but don't have vehicle's size figured in, so I'll have to wait on that, and it doesn't scale exactly to Atlas' core examples.
I also have a section I'm working on compiling and listing and organizing vehicles and vehicles types.
