Vintage Mystery Glow Plug Model Airplane Engine, Great Looking Engine

Description

This is a really nice engine. You can easily see it is new. I can assure you it is more than 30 years old. I do not know where it was manufactured. Some of you model engine collectors may know about this engine. There is number 512 stamped on the bottom of the left side lug. You can see in the pictures that there is a name and number 7 on the right side of the case under the exhaust port.
It turns over fine. Nice engine to add to your collection.
Please look closely at the pictures to best determine the value and condition.
Please take a minute to look at the other engines I have listed. Each is quite nice and I don't think any of them come up for sale very often.
Shipped with USPS Priority Mail.
