Wow! What a transformation!

Perhaps it's time to convert my Whoa Nellie back to a Continental Cafe. Just kidding. I still need to convert the dual player reels to single player.

It turns out that only Continental Café will serve as the donor game.

Before I embarked on my Nellie conversion, I learned that a fellow enthusiast planned to utilize a 1956 Gottlieb Toreador as a donor game. Indeed, that pinsider purchased a second old Gottlieb, in addition to Toreador, when he was unable to find a Continental Café. Long story short, when he discovered that only Continental Café would serve as the donor game, he sold his Nellie conversion items (playfield, backglass, plastics, decals) in recognition that no other game was a reasonable donor candidate.

As I recall, a couple of pinsiders paid well over $1K for marginal condition Continental Café games in 2013 precisely because no other donor game was feasible and Continental Café was scarce. Even with a CC, the project is daunting, because it's not a mere playfield swap. Rather, it's an electromechanical modification undertaking, requiring a scoop alteration, gobble hole ball trough extension, arch reconstruction, a re-routing of wiring sans any schematic, manual or example and a host of other challenging and uncharted tasks.

While I enjoyed the cosmetic conversion aspect of the venture, I had to enlist substantial technical help to complete the project (and it consumed countless hours to complete. . .and it still requires the score reel conversion). Despite the monumental effort to perform the conversion, I am delighted with the result. The game is tremendous fun. At post #8 of this thread, NextoPin posted an article I wrote in 2015, describing the conversion project:

Here's a link to a video demonstration of my game (although the pitch is off and my teenager's videography is somewhat deficient):

My favorite addition to the Nellie game is an interactive topper I constructed in 2015, as shown in the below video:

Now, back to Todd's impressive CC restoration (didn't mean to hijack the thread).

Because Continental Cafe is the only donor game to create an EM Whoa Nellie, the donor game fetched $1,500++ for a beater, during the brief period that a few of us took the conversion plunge. CC was (and arguably still is for a conversion buyer) catapulted into the $1K to $2K range for this unique reason.
However, only a few WhizBang conversion "kits" (i.e. playfield, plastics and decals) were purchased. Also, it soon became apparent that even with a CC donor game, the conversion rabbit hole was immeasurably deep, absent any parts list, schematic or meaningful guidance.

Apart from my EM Continental Cafe conversion Whoa Nellie, and Brad Grant's in California, plus the 2 originals built by Whizbang, I don't know of any other completed EM versions. I know of 1 or 2 other collectors who acquired a CC to embark on the conversion. . .never heard whether either or both completed or abandoned their projects.

Because the Whizbang games each sold for about $15K, collectors were willing to spend a couple grand for the playfield, plastics and decals, plus another couple grand for the donor game (in just about any condition). The problem was figuring out what mechanical and cosmetic parts had to be modified, which parts had to be added and how to rewire the new layout. After all of these years, I still haven't modified the multiplayer dual reels on mine to a single-player configuration.
