I am looking for information on the "Italian M27 Fuze" Spain or "Fuze A" Italy for 250kg bombs.

Hello! I wanted to ask if anyone has any information on the "Italian Model 27 fuse." That's what it's called on the equipment used in the Spanish Civil War. I've located a couple of articles but haven't found anything else. I have one, and it's missing parts, which I'd like to rebuild to have it as complete as possible. It's a fuse that was used for 250kg bombs in Spain. It could be used as either a front or rear fuse, depending on the configuration.

This is an article:

Bomba de aviacion "Legionaria" (Italiana) de 250 kilos

The other is from an e-book:
"Catalogo de bombas y espoletas del Museo del Aire (1913-1939)"

You can buy it on this website:

Catálogo de bombas y espoletas del Museo del Aire (1913-1939)

Los extraordinarios fondos con los que cuenta el Museo de Aeronáutica y Astronáutica, más conocido como Museo del Aire, localizado en Cuatro Vientos (Madrid) son ampliamente conocidos...

Sorry, I forgot to mention it on this site, but I can't find what would be technical data.
This one shows the multipliers and another diagram.

The Italian documentation (Manuale dell'armiere 1931) gives for the 250kg Mle 1928 bomb the "spoleta No 20" - used indifferently as a nose fuse or a tail fuse (with the addidtion of an extension bar) on the 250kg, 500kg and 800kg bombs
Here're the details of this fuze (the text is in Italian)






The British documentation (Italian Bombs and Fuzes, 1948) designates the fuze of the 250kg as "Type A" for teh nose fuze and "Type O3" for the Tail fuze ( gifven as a"modified type A")





And these are the "tavole didactiche" from 1939 on the 250 and 500kg bombs with details of their fuze:



The Spanish documentation for 1945 gives indeed for the "modelo 15" = Italian pattern 250kg bomb, the "Espoletta No 27"

Thanks Dreamk, I'll take a closer look, but I don't see any measurements of the internal parts. I think your images are better quality than mine (I could also make the parts by measuring and using a rule of three). I'll still look at it, and as I said, thank you very much.
