Are you looking for an appraisal? If so, there's a dedicated thread for that here: http://www.pbnation.com/showthread.php?t=3657046
If you're trying to sell it, I would suggest posting it in the Rare, Classic and Vintage Marker BST
section found here: http://www.pbnation.com/forumdisplay.php?f=923
You can also post a link in the AKA BST links only thread
found here to generate higher viability: http://www.pbnation.com/showthread.php?t=3552895
That's actually a '00-'03 Excal. The milling is referred to as a "full mill". You'll likely want to note what anything else that may be included such as the matching Javelin barrel and AKA padded gun bag. If you're able to determine what type of solenoid and board it has, that would be useful information as well. Also, please note the this forum requires you to list an asking price. Also, sale threads are not allowed in this section, so I'd suggest starting one in the one I referred you to above. Nice looking gun and good luck selling.
PS. If you decide to part out the barrel pictured, I'd be interested depending on the bore size(s) of the back(s) and price.
