As I have been collecting from both sides, the following images belong to a Self-Propelled Howitzer M-110 A2. This vehicle, was (December 2010) in a junkyard nearMadrid. I saw at least three of these mills in the scrapyard. The photograph was thebest preserved, since the other two were already in process plants.
In 1973 he came to Spain 12 Atp's M-107 that were assigned to different units(including the RACA 41). Later, in 1988, gives them a piece of 203mm M110 A2 and renamed. According to some sources, the Spanish Army have reached up to 64 of these units.
As a curiosity, note that the guns of the retired military M110 USA, were reused ascovers for the manufacture of the GBU-28 bomb antibúnquer.
Por desgracia, estos artilugios llevaban demasiado tiempo en el desguace y su deterioro ha hecho, que al menos yo, no pueda identificarlas. Os las dejo por si alguno lo consigue.
Unfortunately, these devices took too long in the dismantling and deterioration hasdone so at least I can not identify them. I let them in case someone gets it.
