No need to presume, it says Erik Hoglund on the label and is engraved with the appropriate mark.
The /16 or is it /165 refers to the size (approximately) so about 16cm in diameter?
The design date is probably late 1950s, it may be possible to date production by the style of the label but I don't have that information, my guess would be late 60s or very early seventies.
Display the bowl in a window, that amber colour sparks into life with a bit of sunshine.
