Lucky or being in the right place at the right time.
I had purchased a glossy K & C Pacific pilot via eBay from a collector in Pennsylvania (might have been the second item I purchased from him). Anyway, he later contacted me and said he had a K & C plane that he'd like to sell. I think he was looking for more than I could afford to pay at the time so I put him in touch with Louis and they worked out a deal. Then, either Louis or the collector contacted me saying he had an Elvis and a Beatles set and he was going to give me first dibs. The other one would go to Hans. Would have liked the Beatles but, again, being a little short on funds, I chose the Elvis.
I've seen the Beatles set on eBay a couple of times (it's on my most wanted list) but have never seen Elvis.
