Decades ago, a buddy had built a Volmer Sportsman amphibian. It had an O-200 engine and he felt that it was underpowered. He came across a Lancer whose owner had already sold the engines, but had everything else. My friend bought the wings, complete with cowl and FWF stuff, less engine. He sent me a photo of the Volmer with both cowls on and the existing engine on, too.
Would have been a 3-engine amphib but he never got the engines, just not enough money.
Years later, when he could have paid for it all, he was having too much fun with other airplanes and the Volmer had been retired.
I wish I still had that photo.
