Here we have two more Russian engines. One is "pristine and un run" the other (with the replacement unadonised spinner) is used.

Although these are both tight and look well made - there is an odd finish applied to the crankcase. It is flaking away on both engines.

The finish reminds me of a new galvanised bucket!

These look like Yin Yan Silver Swallow diesels.

Very similar but the Silver Swallow has a much better crankcase and is better finished.
