A Blue Bird conventional on the International 3700 chassis with an auxiliary manual transmission and a 2-speed rear axle.

The 3700 was the lower GVWR version of the 3800, just like how the 1723 was the lower GVWR version of the 1753 when it came to the S-Series.

A School Bus chassis with an auxiliary manual transmission and a 2-speed rear axle has always been a rarity, and always had to be custom-ordered.
