I remember having my uncle drive to about 7 or 8 Gulf Stations to get one of those paper Lunar Modules, but I always wanted one of those Grumman Contractor Model LEMs but didn't know how to get one. About 15 years ago I met someone who still worked at Grumman in their model department and after I brought up the topic, he offered me a pristine contractor LEM model made in the late 60's as well as the original proposal model made in 1962 that Grumman provided along with their written proposal to NASA. It looks completely different than the final version, but it won them the contract, making Grumman the pride and joy of Long Island.
The proposal model he came across was still unpacked in its original box and looks as if it was made yesterday. It is by far and away the rarest of the Lunar Module models with a round green lucite base that says "Proposed Lunar Excursion Module" with Nasa and Grumman logos. Incredibly, it had been stored away since the early 60's with no one at Grumman knowing it was there until then. He was packing up models, as they were shutting down the Grumman model department following their merger with Northrop, and was nice enough to call me to ask if I wanted it as he knew from our conversations how much I liked the other LEM model. He also included a few of the bases the final version LEM came with depending on the year of manufacture, with varying logos and sayings, as well as a smaller LEM model, a mini version of the larger contractor model. These models sit proudly in a model case and remind me everyday of all the wonderful memories I have of all the Mercury, Gemini and Apollo missions. They sit right next to my personalized autographed photo of Neil Armstrong, which he was nice enough to send me years ago after I wrote him a letter.
Here's a link about the history and development of the LEM for those interested.
