1984 LEGO 6080 King's Castle w/ Box Excellent Condition

Offered for bid is a 1984 LEGO 6080 King's Castle Set . The set is in overall excellent condition. It's missing 1 mini-figure red triple plume and 1 mini-figure blue medium plume. I can't find them, and I don't know what happened to them. But everything else is there. The box shows minimal wear, and has the original "Service Merchandise" sticker on it. The set includes the box, instruction, and a book on other sets available at the time.
I have a lot of LEGO sets ranging from the mid 1980's to the mid 1990's. Mostly Town & Castle sets. Some old Space sets & some Pirates. Most sets are with the box. I'll list others as I go through them & make sure they are complete. I'm trying to get rid of old toys I had as a kid to clean out the house. If it matters to you, all my sets come from a smoke & pet-free home. Shipping for this set is $12.00 with Parcel Post within the U.S. I will ship outside the country, but I will have to find out how much it will cost. I will also combine shipping for multiple items. If you have any questions, feel free to ask. Thanks!!
