Safeone they also made a load of models with similar trim to the old SLS’s, with the similar large disc handle, but one easy feature aside from the obvious bolt numbers, which will determine if it’s old run or new is the hinges.
If the underside of the hinge carriages are chamfered to the door then it’s a modern run SMP based on their Euro graded Community range. The chamfers deflect mechanical jacks and roller pry-bars etc preventing any real ‘purchase’ on the door, but none of the original SLS had this feature. Hope this helps, PM if you want as I am very familiar with working on both makes.
