  In present paper we construct classical and quantum models of an extended
charged particle. One shows that consecutive modelling can be based on the
hollow thin-wall charged texture (in the hydrodynamical approach of a perfect
fluid) which acquires gravitational mass due to Einstein-Maxwell interaction.
We demonstrate that such a model has equilibrium states at the radius equal to
the established classical radius of a charged particle. Also we consider
quantum aspects of the theory and obtain the (internal) Dirac sea conception in
a natural way. Besides, the phenomenological unification on the mass level of
the two families of elementary particles, charged pions and electrons and
positrons, evidently arises as the effect induced by classical and quantum
gravity prior to Standard Model.
  Finally, in the cosmological connection our model proposes the answer on the
important question, what are the real sources of texture matter. Besides, the
texture hypothesis means that in the early Universe the topological texture
foam phase existed before the lepton-hadron one.
