Bomb Identification needed

[Dreamk]

Can someone identify teh bomb lying on the ground on this photo. The photo was (supposedly) taken in Poland in 1939 and shows a PZL-37 Loz bomber with a bomb on the ground




The bomb is in 2 parts - the tail being separated and looks very much like the Tolfvan models (fins with the typical rotation foldings, circular collar at the front of the tail) . The only two parts Polish bomb known in the 1930-39 period is the 100 kg Ż wz. 31 but it is supposed to look very much as the French 100 Kg bomb from the early 1930s, if we are to trust its drawing

Most Polish bombs were PuW type. I think we can also exclude the BS series that never entered in series production, but had cylindrical bodies and a fin similar to the czech Skoda bombs the late thirties, if we trust its drawing (once again, so long I have not seen photographs of these bombs, I am always cautious with drawings, even when they come from the most respectable sources)



So what may this bomb be?

It is Polish 300 kg PUW bomb.

Thanks, but allow me to disagree





The rotationary fins were indeed developped first on the PuW but were adopted widely in the 1920s and 1930s (Bofors, Tolfvan etc...)
The collar junction of the tail with the body does not fit the PuW 300kg identification , nor the shape of the body and nose, nor the overall size of the bomb.

PTW there is a funny thing on the second schema - the larger PuW are called "German" bombs, by opposition to the smaller weight PuW poduced in Poland, but the Michelin flare bomb is not called "French" nor "Michelin" - these schemas came from the official leaflet of the Polish Air Ministry from 1928.

An interesting feature on the photo is the red arrows pointing to the townend collector ring supports on the Bristol Pegasus engine on the Pzl 37,also all the various inspection panels and hatches are open,it looks like the aircraft is getting a thorough investigation,

I must recognize that the pics you brought here make indeed the case for the PuW 300 its seems it's even the very same aircraft!
And the pic of the 100kg wz31 is a great addition too. thanks!!!
