Dear colleagues,
Would anyone happen to have Vājapeya 1955 Performance Committee manual:
The Śrauta Ritual and the Vājapeya Sacrifice. Poona: Vājapeya Performance Committee, 1955 . 
And the film by Dr J.A.B. van Buitenen of the Vājapeya in Poona and 
13-page unpublished  typescript "Vajapeya: English commentary" (1956)  accompanying the film.

With thanks and best wishes, 
Yours,
Natalia Korneeva
