Assume that $K$ is an~arbitrary field. Let $(I,\, \preceq )$ be a poset of finite prinjective type and let $KI$ be the incidence $K$-algebra of $I$. A~classification of all sincere posets of finite prinjective type with three maximal elements is given in Theorem~2.1. A~complete list of such posets consisting of 90 diagrams is presented in Tables 2.2. Moreover, given any sincere poset $I$ of finite prinjective type with three maximal elements, a~complete set of pairwise non-isomorphic sincere indecomposable prinjective modules over $KI$ is presented in Tables~8.1. The list consists of 723 modules.
