Need help re Italian taxation of U.S. pensions (Florence)

This fall I will be retiring after 15 years as Professore di Genetica at the University of Siena. Soon thereafter I will start to receive annuity payments from two U.S. Employee-sponsored pension plans. Article 18 of the U.S.-Italy Convention for the Avoidance of Double Taxation and the Prevention of Fraud or Fiscal Evasion" (current version ratified in Protected content that Italian taxes be paid on that income and Article 1, paragraph 15 of its Protocol equates these pension plans to "fondi pensione".

So far, I have been unable to find a commercialista who actually KNOWS how that income should be declared so that it is treated as income from fondi pensione (pensione integrativa o complementare). I have contacted most or all of the lawyers and accountants on the U.S. Embassy lists in the provinces of FL and SI with few replies and less success. If any of you are a commercialista with this specialized knowledge, or know of one, I would appreciate hearing from you.

Sincerely, Lenny Robbins
