Going by the seller name it’s the same guy that had posted up a full load of bikes pictured together, that were his uncles,but the pics were not his although he said he had taken the pics after getting them out the lockup.
Advert pics were from original owners garden that he sold them on yrs bk.
Once u get a price in mind just adjust ur advert,add in plenty of picture's,good description,price ,Location ,whether u are willing to post or collection only etc.
U could get it sold easier by splitting it,as the parts may help others complete builds of their own builds.
Price wise there is a section on here What’s it worth that u could put it on
