Looking for ALV subgroup A clones

[GAGNONCC at NCCCOT.AGR.CA]

	I am looking for a source of subgroup A avian leukosis clones.  The
portions of the genome that I am most interested in are the LTR region, the
leader region and the envelope region.  So if the entire genome is not in one
clone, no problem as long as one of the portions listed above is in there and
there are no intentional mutations incorporated.  A history of the clone would
also be required.

Thanks for any information in advance,
