Bombs designs - Spanish Civil War - Industries Catalunya

[Dreamk]

Thgis document was published on a Spanish forum ("Griegc") focused on artifacts related to the Spanish Civil War.
It apparently shows projetcs of developments of aerial bombs by the war industries of Catalunya, at an early stage of the war.
Can someone throw more light of this ?
What can be the meaning of "municion B-G"

Just a guess, but I have seen similar usage in manufacturing documents (including Spanish and Italian technical drawings) indicating the different designs or 'schemes' or 'esquema'. In this case the top left would probably be design/scheme 'B' and the bottom right would be design/scheme 'G', with design/scheme 'A' possibly being already in existence or discarded.

So possibly:


Though the designs/schemes may be in a different order than what I marked up.

I already thought about that but there are 8 bombs and 2 grenades not 7 bombs only.
The formulation of the title is also very specific : "of THE munition" , not "of munitions".

A careful examination of the images enble to see that a common point of all these munitions is a special envelop of the explosive body, thick black layer with small white pellets inside. By contrast, the frontal ogival dome is homogeneous greyish. This leads me to think that we are speaking here too of a pattern of of fragmentation devices using an envelop of beton containing pellets of metal or stone - like the Swiss Schleuderbeton SplitterBomb and the German SBe-50 and SBe-250.
The "municion B-G" may tehrefore be a designation for "Betun y Grava" (although Betun is generally translated by bitumen, the expression "betún con piedras" or "betun con grava" designates what is called beton or concrete: a mixture of cement, water, and aggregates like gravel.

This would be consistent with the circumstances surrounding this drawing: the need to improvise very fast adequate solutions to a war situations while resources are limited.

Ah, that makes sense. Similar in concept to the German SBe (Splitter Beton) bombs then.
