G'day
Looks like an English Frog 1.49cc "Vibramatic" diesel from the 1950s. I used to have one of these. They run quite well. They have a flutter valve induction system like the small Cox engines.

There was also a Frog 150 which looked similar but had a conventional front induction arrangement. One of these was the first engine I ever started.

Thanks a lot Mike !!!!!!!!!!!!

Edgardo.-

The Frog 149 Vibramatic was made by International Model Aircraft between 1956 and 1962. I agree with Mike that it's a nice runner -I still have one. Enjpy!

Cheers,

Adrian

Here's mine. Bought it used from a friend about 45 years ago. The mounting holes were enlarged and the conrod lower end shows some wear...but still runs.

I think a company in India made replicas for awhile, also.

Hopefully copying from another site that copied from some one else is OKhere!
