Engine nr?

I have bought an 45" engine with the engine nr 42W-xxx. (The x`s stands for numner wich I dont wich to type.)
The number look real good and original to me. Anyone who might know what this might be? Falce or ?

Please post a photo of the whole number --- cover up the last two numbers if you think its necessary --- or else tell us exactly what the numbers and letters are (leave out the last two numbers if you want to). No one is going to be able to tell you ANYTHING about your question without more information. You have not given us enough information.

The engine nr is 42W-37x
The - is in center, so it doesn`t look like an L missing the upright part. Area around the number are flat and nice so
it does not look tampert with...

WLC,

I stand corrected and I apologize for my tone ... You did give us all the information, and I haven't a clue ...

If the engine number just has the W in the prefix it represents a low compression 45. None are listed for US production but there have been others appear that were for export. Very little info exist for export models but search this forum for more info. Some South American and Asian countries ordered 45s for various duties. I would consider it a very rare piece if the numbers are an authentic stamping. But despite your description, without pictures it is impossible to tell if the numbers are original or just stamped on Military surplus blank cases.
So no pictures, no proof!
