The 35s is the standard model in Beech as you say, the early Luxus is in Walnut as IJ's lovely example.The later Luxus is also Walnut but no finger grooves & sporter cheekpiece.
Sling swivels are on both the Luxus & Export with an option of the 22" barrel.
Early UK advertising mislead people into thinking the Export was only in .22 with the super long 22" barrel which is not correct.
The seventies models - HW35S
HW35L
HW35E
HW35LS
