If you are not familiar with Eduard kits then you might be confused by the differences between the five different types of kits that Eduard produces. (Content paraphrases content on the Eduard Website)
Overtree kits are very basic in content, with no reduction in the quality of molding or fit. There are no instructions, no decals, and no photoetch or resin. For a rather low price one gets the parts trees and that’s it. We are talking a price in the range of $15.00 for some excellent parts sufficient to produce one model of high quality, but you will need to supply the instructions and decals from other sources. Overtree kits are not necessarily “easy” or “easier” to build than other Eduard editions of a particular subject, they simply contain the parts for one model and nothing else.
