I love the sound of a real Spring Reverb, and I chanced upon a self build project from a company called Surfy Industries. They sell kits for a spring reverb and Tremolo, which are small circuit boards that can be mounted in any enclosure you like. I saw on their forum that there was a trend to build them into Toolbox's which is a great idea as its long enough to hold the Reverb pan.
I know there have been many requests for a Spring Reverb on the forum and I can wholeheartedly recommend this kit. It is well priced, simple to put together and the customer service is top notch! The Tremolo is fantastic to, giving you both a Blackface and Brownface style.
There is a picture and short video demo below, forgive me, I couldn't find a toolbox in Green!
