Vintage crossbody monogram navy purse

Not familiar with this brand but it was an awesome flea market find. Features a double clasp closure and opens up like a coin purse and has a metal upper skeleton that holds the bag open (see photos). Lining has some tears. I’m not certain how old this is, best guess is mid 80s. Outside is in excellent condition, no scuffs or tears Measurements Length 11.5” Height 8.25” Width 4.5” Strap length (not adjustable) 24”
