Hi Nick
Evgeny Velichko posted some information (later edited by Francisco) that Oberleutnant Werner Mölders engaged several I-16 fighters and was responsible for the loss of various of these on 13 September 1938. Apparently, Teniente Jaime San Colom of the 7ª Escuadrilla was shot down and killed in CM-125, two other Moscas were shot down as well (CM-154 and CM-178) although their pilots bailed out, another pilot of the 3ª Escuadrilla in CM-138 was wounded and Andrés Fierro Menú of the 3ª Escuadrilla landed by error in CM-192 on a Nationalist airfield. You can find the original information at:

Horrido!
