Reminds me of the US Navy's AP bombs, such as the 1,600 lb MK 1 (various suspension configurations) and the AN-MK 1 version.
Image of the AN-MARK 1 MOD ? (can't see the MOD number).
The MK 1 series certainly had a version with suspension bands like this those seen.
There's also the 'smaller' 1,000 lb AN-MK 33. I presumed there's a MK 33 version, but I've not found it, but can check tomorrow.
Image of the AN-MARK 33 MOD ? (again I can't see the MOD number).
A scaled version of you image below. For note there's no geometric correction in the scaling, as such the bomb should be slightly larger as it's behind the ruler.
The AN-MK 33 bomb's dimensions; a diameter of 12" (305 mm), and a bomb body length of 59.75" (1,518 mm). The MK 1/AN-MK bomb's dimensions; a diameter of 14" (355 mm) in diameter, and a bomb body length 68.9" (1,750 mm).

Probably a Soviet (Russian) RBK-250 AO-1 (РБК-250 АО-1) dispenser bomb.
Thanks, the AN-MK 33 was my best guess, but I have to completely throw out the measurements listed. Errors occur sometimes though, and that is what the scale is there for.

Going by the bands I'd say it was probably a MK 1 ('Type A') 1,600 lb AP bomb.
As to the ruler, they can be helpful, but without software that takes into account geometric errors, or manual mathematical correction, it's only a guide. If the ruler was placed on the central top of the munition, it would give you a better estimate of length and diameter, but again, there will still be geometric errors. In reality you need the ruler, the position of the ruler in relation to the munition and camera, and the position of the camera.

The small one appearsv to be a French 50kg DT2 - dimensions also are compatible - diameter was 195mm and length 1180 mm without fuze.
This was the "staple food" of French aviation from the last stages of WW1 till... the early sixties. A very efficient HE device with grood fragmentation - its efficiency was often assessed by French authorities as being greater than the later developped 100kg HE bomb
The 50kg DT3 looked identical but the diameter was 200mm (same length) however this bomb was an interim model with its body made from recycled oxygen cylinders and saw service in relatively limited numbers, being perimed by 1939. However the reinforcing struts of the tail are more compatible with the regular DT2 models.
The large one is apprently the body of a French 100kg bomb - diameter is correct (275mm) and length 1038 mm. The oscillating suspension ring is also quite characteristic
Colour of the body of the 50kg DT2 (not the tail) is close to the original (all the bomb was painted in mustard-yellow)
The green body of the 100kg bomb is nother issue - although these bombs were by regulation also painted overall mustard-yellow (or white or black for exercise/inert bombs) at the beginning of teh 1930s, a batch of old 100kg bombs undergo overhaul with replacement of the explosive and was painted "grey-green" - thsi was supposed to be a lighter shade than what is present on this sample bomb but in the absence of an original comparaison model, who knows...
