Default Mystery diesel

Here's me asking a question for a change. A friend of a friend fired the attached photo my way yesterday asking if I could identify it. I can't-but my best guess iis something of east european origin. The resemblance to the Rivers Silver Streak Mk2 is very strong-(crankcase, prop driver and spinner) but the fins are all wrong. The original SS and CS replicas were never coloured. I don't know if it is roller bearing, ball raced or whether the apparent front ball race housing is there for cosmetic purposes only. Certainly the designer was clearly influenced by the Rivers design. The owner is proposing to use it in FF scale. Anyone got a positive ID? Jens Erik? Dave Owen? George/

Some features suggest it could be ZOM, Spanish 2.5cc diesel. If it was it could be a Mark one. I have a Mark 2, and there are a few pics on Ron Chernich's web site of Mk2 and later ZOMS. Otherwise how about a FOK from memory they also look like a ZOM.

The pic below shows a ZOM mk2 from Ron's site.

What does the writing on the crankcase say?

It's definitely from outside the Anglo-sphere. I can't find any pictures of a FOK, like ZOM's they turn up regularly on ebay. I'd guess that both of these were heavily influenced by the German Webra MK2, which in turn was an interpretation of the Oliver Tiger/Rivers TBR diesels. The Webra's seem to be much rarer these days.

FFkiwi, is right it's going to need David Owen.

Does the other side have any markings? "MM" perhaps. It looks like a 1975 Micron team race diesel. French made.

Good old Dave Owen-he sent me a pm.-FWIW guys-and to put your minds at rest-the mystery engine turns out to be a French Micron TR diesel. I had a little niggle that it might be a Micron when I first received the pic-but on checking Clanford's book there was nothing similar in the Micron photos, so I assumed I was wrong.

The photos on this site show the much more common plain bearing "Sport" version of the 2,5cc Micron.
It came either with plain or red anodised head, while the "Mistery engine" is the double ball bearing "Racing" version, which came with either plain or blue head.
"MM" on the side stands for "Micron-Météore", Mr Gladieux's Micron company having absorbed Mr. Maraget's Météore company at some point.

Is there an echo in here? Does it have "MM" on the other side?

Of course it does have MM on the other side.
"2.5 R" on the right side is enough to positively identify the Micon 2.5cc series.
Plus I have had two of those. No mistake there.

Here's one with a purple head;

It´s an LD 0.1 cc (.006 c.i.) diesel made by Ladislav Davidovic in the Czech republic, very real...

Balsa works - a delightful little engine!
Is that a cox grey 3x1.25 prop?
If so what kind of revs does she turn?
Thanks Rob

Hi Rob,
yes it's a Cox 3x1.25 grey and it turns @ 10.000 rpm, which is just right for a small free flight plane. It is relatively well-mannered for such a small engiene, but it needs warm and dry weather to start.
The Comper Swift is 18" span and weighs 1.75 oz.
The front of the Comper is so saturated in castor now, I'll have to retire it and build something new. Just a little more wing area and a touch lighter would be nice. The nose will need to be short for good balance and it must be streamlined because of the tiny prop.
