The type of bottom bracket assembly/crankset found on this Wards Styria product bicycle is termed variously "Thun pattern", Thompson and Thompson-Simplex (no relation to Juy).
Here is a photo of a fully cottered version so you can see the bearing arrangement. Bike under discussion has spindle permanently affixed to the right hand crank arm.
