The Royal Diana portable typewriter was made in Holland by Royal-McBee Nederland N.V., a wholly-owned subsidiary of Royal-McBee Corp.
The company had originally been Halberg Machinefabriek (founded 1941), which produced the Halberg Traveler until Royal-McBee bought it out.
The serial number on this Diana model is DOP 86199, which suggests it was made in 1959 or 1960. On September 10, 1959, the Toledo Blade newspaper ran an advertisement for the Royal Diana, giving a price of $79.50, a reduction of $50 on the "regular" price.
Will Davis on his Portable Typewriter Reference Site features a Royal Diana with the serial number of DTE 85312, which he says indicates perhaps a 1959 or 1960 production. Will’s page on the Diana is at http://machinesoflovinggrace.com/ptf/Diana.html
It features a typewriter with a Royal-like Diana logo:

Georg Sommeregger tells us on his site http://www.typewriters.ch/collection/halberg_portable_typewriter.html
that Halberg Machinefabriek N.V. was first established in Limburg, a province in the deep south-east of Holland. Its directors were called Van Halder and van den Berg (from which comes Hal-Berg).
The company went public in February 1950 and started production of typewriters in 1952. In 1953 the factory moved to Cuijk, a town in the south of the Netherlands. On November 29, 1954, Halberg’s typewriter division and factory were taken over by Royal.

Here is a Royal Diana I found for sale in the US. It looks like an upgraded model, more like the one in the 1960 ad than mine:
