CD 528 unmarked and in mint condition. Almost 2-1/2 inches tall, base dia. is a little over 2-1/4 inches, and the color is green aqua. Made in France, reported to be used in the Sahara in Algeria. Seen this in a catalog priced at $600, saw another on ICON for $300, and one just sold on eBay for around $200. So, how about $150.00 with shipping included. Email me for more pics. Satisfaction is guaranteed.
