From CC Valandil to AC Manco Capac

[The Rock Doctor]

What can I say - I like to keep people on their toes.

Jef, what software do you use?

I use an old PCB software, just the library part.

Here is AC Manco Capac
ex Valandil enter jan 1918 in Callao Shipyards for modifications to standard of the Peruvian Armada.
- New 230/45 mlle 1916 take the place of the old 9"/42-Mlle1893
- New 120/45 mlle 1905 QF take the place of the old 4"5/42-Mlle1891
-New 40MlleAA 1916 take the place of the 38mm from Rohan
- Cage mast are removed & the classic circular light top blockaus take those places & not so high.



The calculation give:
875t in all - 637t for the guns & 238t for new equipement.
cost 1.75$ - 0.875BP
