Cam specs ??

[SunbeamAlpine64@aol.com]

Hi 
A whille ago I bought what I was told was a Holbay Stage2 Cam from Sunbeam 
Supreme and was suspicious at the time because it looked exactly the same as 
the std cam I'd taken from the 1725 engine and had the same numbers on it 
:1981080 and MC24235M   

Does anyone know if it `could be` the genuine article or have I been sold a 
dummy? 

Cheers
