enya 60-III
 

I am looking for some information on an engine I found in some of my grandfathers things after he passed. I found 2 brand new in the box, still in a plastic bag engines that are made by enya. On the side of the engine opposite the exhaust, it's labeled a 60-III model 7033. I am looking for an approximate age of the engine and what a current value might be. Is it considered a collectable? Any help would be appreciated. Thanks, [email protected]
