I would be a bit suspicious. To get a good I idea you would need to actaully handle the uniform as photgraphs can sometimes be misleading. The cap doesn't look too bad but I would like to see the markings on the inside and any signs of wear before I bought it. The same goes for the uniform. Can you get any further photographs? How much are they asking?
Difficult to say without seeing the inside of the cap to determine the year of maufacture and maker. Also, I would like to inspect the buttons for a date of manufacture (if there is one there). It looks like a M1958 cap from the photo which if it was the case, would make mean that the uniform would have been replaced at this time and so the cap does not go with the uniform.
