Purchased this directly from Werner Wigger in 2015 and have only run it maybe 6-8 times. It is jewel like in it's precision build quality.
The following YouTube link shows it fully, so no extra photos:
I paid $1500 USD for it in 2015 and ask that exact same amount today. These are no longer made and very hard to find...this is in virtually NOS condition. Comes with a custom plexiglass case which fits onto the engine's wood base. Shipping will be $75 USD within the US and $125 USD for OUS.
