In 1927 the line was expanded to include a 12
to 14-passenger bus known as the Utility Coach in advertising but officially designated
model D. The 21-passenger city body had become known as model B and was called the
Pay-Enter Grand body, while the 21-passenger highway design (model C) was referred to as
the Observation Coach. Small model D's were sold for transit and suburban use as well as
over the road. The 17- passenger transit style body (model F) continued to be produced
until 1928, though it was seldom mentioned in FitzJohn advertising.
Larger buses were coming on to the scene, and FitzJohn offered model K, a 25-passenger
city and suburban design, and model L, originally a 29-passenger intercity bus intended to
compete with the products of such larger builders as Bender and Lang. Only a few full-size
model L bodies were ever built, and FitzJohn concentrated on a 25-passenger version.
