Three survivors - Churu, Bareilly, and Rae Bareli - were sold to Peru in 1937. As part of the sale, they were "refitted", at about 17.5% of their cost.
No beans there. In the Indian
Q2/37 sim report, the ships received 270t in their rebuild, which is 16.8%. Perhaps India extorted some spare tonnage out of the Peruvians. In any case, it's still over the 15% mark for a Level 3 refit which allows the retrofitting of an armoured belt, so that shouldn't be removed. The belt was definitely stuck into the design by Howard (who bid on the design and did the Springsharp). The DP guns on the Apurimacs were replaced in the same refit, per Howard's specifications. So replacing the sim with the specs from the Indian encyclopedia will just replace a suspicious sim with a flat-out wrong sim.
I've no idea about the engines - I didn't dig back that far.
