Hi!  Thanks for taking the time to look at a RDKL, Inc. auction!  I have great feedback because my customers are happy with my customer service and detailed product descriptions.

Poor condition with many blemishes, but appears to be mostly intact.  Please look at the pictures and judge for yourself.

Please let me know if you have questions.

Thanks!
