I think a little clarification is necessary because this last post makes it seem like this is your snake and now you're not sure on the blackhead?
Are you looking for something to compare for a morph ID?
Are you buying this particular snake?
Are you selling this snake?
It looks like we are all under the assumption you're buying. If you are selling...be aware that we still could be off on things and that unless you are one of the top breeders, it may be very hard to get the prices that we mentioned. Until you build up a name and reputation, it might be easier to go with a lower price at first. Or start with the higher price but entertain offers on it.
