The ARVL is somewhat of a rare bird although as Rob as stated there is information available on this vehicle type. My count tells me that there were 37 in the CF and originally the ARVL was based on the M113A1 although beginning in the late-1980s these were upgraded to M113A2 with two different ECCs for this vehicle type. My records tell me that they were all disposed of in the 2000s with the last one in 2012. Which one do you have access to?
Here are a few images from my collection.
