[Dean launder]

Hi I was wondering if anyone could tell me what year this bottle is from and a price on what it's worth if anything, I have not seen one like it and am beginning to think it quite rare. Thanks in advance. Dean

The bottom of the bottle says sc303 A 163
Having problems uploading a photo but the neck on the bottle is very long and twisted I will try and upload using a desktop computer later :-)
