I've just received a few pics of a small rocket motor, from a friend of
mine.


Long shot - but I think that text is 'SN634' on IMGP0495 right hand
side - speck of dirt at top left of the 'N' making it look like 'iY'.

Looking for more now - and the writing looks Aussie :-)

Are bolts metric or SAE? SAE would probably mean US; metric would be
inconclusive.

The mounting bracket appears interesting- is it rusted, coated, or
eroded in some way?

My guess is that is not US military or NASA since an assembly this size
would have a part label with part number. Unless of course it was made
by the aliens at area 51...

Hope you find the answer...
