I'm also selling my first release copy of the American Airlines 737-800, G2AAL015 - complete with original box, removable landing gear, and landing gear replacements. The beauty of this model is it features absolutely ZERO tarnish and is in impeccable condition.
The asking price of the model is $200 USD INCLUDING USPS priority shipping to US addresses. I'd prefer to ship to only US buyers, but if you're interested and not in the US, get in touch with me and we will work on a shipping quote. Price is also (reasonably) negotiable, so please reach out and we can try and work something out.
Please reach out to me via PM if you're interested!
