Italian midget submarines CD

[de domenico]

In 1942, Campini and De Bernardi prepared a blueprint of a one-man, 6-ton midget named CD. It seems that a prototype boat was built by Caproni at Taliedo or Rovereto and proposed  it to the Kriegsmarine , which tested it in Germany about Nov. 1943. Following the testing, the KM seems to have given to Caproni an order for 50 boats in Dec. 1943. One or two such boats were at Riva  del Garda in April 1945 and were scuttled in deep waters in the Gardasee.
Has anybody found any  documents in German archives about this order?

plans were also given to the japanese
and about sea Trials in Lake Garda with 2 experimental boats designed by CAMPINI

Hello,
sorry, I have no other sources .

proposed  it to the Kriegsmarine , which tested it in Germany about Nov. 1943. Following the testing, the KM seems to have given to Caproni an order for 50 boats in Dec. 1943

On which source based your informations, the same as me, the japanese Naval attache ?
I could  not find the date "Dec. 1943"

My information comes  from documents  collected by   local archives at Rovereto, and currently under closer scrutiny.

in this case, page 2 from japanese Naval attache ,
it fits together with your informations
