"As I recall from the pre VCII days, the priest carried the offerings with him when he processed during the Entrance dialogue, but I am no longer sure."
As a former altar boy, Orthodox and Latin Rite from those halcyon days, I can tell you that your memory is right on the money. At both a High and a Low Mass, the priest carried the chalice and the host on the patten to be consecrated. They were covered by a veil of sorts (the pall?) on top of which was the corporal, I think. When it was set down on the altar table in front of the tabernacle, it looked like a trapezoid. The ciborium, as I remember it, was in the tabernacle.
How good is my memory? :)
You are correct. In fact, some priests still use the veil (simply called a chalice veil). The chalice, with the purificator, the paten with the host resting on top of it, and the pall on top of the whole "package," are covered by the veil, which is the same color as the vestments of the priest. In addition, a "burse," a flat cloth container, which contains the corporal, on which the consecrated host rests during Mass, is put on top of the chapel veil. The wine and water are usually put on the credence table before Mass. If more hosts need to be consecrated, a ciborium full of unconsecrated hosts, is placed on the altar before Mass.
