This is a photo of R. Kirkwood at his breeding facility in Richland around 1999. His lines included

Alligator, Nigerino, Spike, Maverick and combinations of the 4. These lines date to the 1980's and

prior. To this date, the lines have remained intact and authentic. Thank you Mr. Kirkwood for all the

fine animals and all the knowledge that you shared with us. RIP. To view pic of
