After some extensive research I have gotten confirmation from a person who was instrumental in purchasing at Harbour Lights. He confirmed that the actual number produced and sold of AB122 Lightship Overfalls and AB123 Tender Narcissus were only 500 each. AB124 USCG 87 foot Patrol Boat had only 300 produced and sold!
We have available directly from the old Harbour Lights storehouse what may be the only AB124 counter sample in existence! Available at the following link.. http://www.thecapecodstore.com/harbour_lights/cs_87_foot_patrol_boat.html
