Query: 2(2S+1)-Component Model and its Connection with Other Field Theories   This talk presents the review of forgotten but attractive formalism proposed
by Joos and Weinberg in the sixties for description of high-spin particles.
Problems raised in the recent works [Ahluwalia {\it et al.}] are discussed. New
results obtained by the author in his preceding papers ["Hadronic J.", 1993, v.
16, No. 5, pp. 423-428; No. 6, pp. 459-467; Preprints IFUNAM FT-93-19, 24, 35]
are reported. In {\it Appendix}, bibliography of publications related with
mentioned $2(2S+1)$- component formalism is presented.
