Purse Chanel, Large authentic????

Large quilted diamond design base exterior, 16 inches wide and 11 inches in length Chanel labeled VINTAGE purse, wow huge and can carry in it everything!!!!!! Hardware chain and leather straps, hardware is heavy and sturdy, leather shows is intact, due to lighting chain appears rusty, DEFINITELY NOT. The exterior leather shows some very, very minor flaw due to rubbing against other objects and age. Interior is beautiful leather suede with two large zippered compartments on either side, pull zippered closing with long leather tassel attached to gold colored hardware with double CC. I purchased this bag from Offer Up website and the seller advertised as her having bought from estate sale and I purchased as such. Actually the color is midnight dark navy blue or black.. considered large Xlarge, very roomy and accommodating. The price reflects discretion, she listed as 485.00 Any questions, please ask. Thank you
