15 cm pevnostní houfnice

15 cm German strength howitzers for revolving towers
The gun was created at the beginning of the nineties of the nineteenth century in the design office of the Krupp arms factory. It can be assumed that its development and production were carried out in parallel with the heavy field howitzer, which was introduced into service in 1893. It is interesting that compared to the field version is a strength weapon identified only as spired howitzers, without any additional data.

Vážení,
nedávno jsem nalezl na internetu několik zmínek o pevnostních věžových houfnicích firmy Krupp, které byly označeny jako: Modell 1893, 1895, nebo 1897. Prosím těmto informacím nevěřte, jedná se o lživá tvrzení, která jsou v rozporu s britskými, francouzskými a německými údaji.
