I am not entirely sure but I think later on in the production run the Olympic might have been fitted as standard on the NJR100's
The first Shamal breech blocks were steel, then later brass. Early 100 Series guns had brass breech blocks which was later changed to alloy. The early Shamals had a wider scope rail as well.
All Shamals have the name engraved on both sides of the breech block - the font style changed across the production run. The 100 Series use the sticker system on the breech block as a cost measure when designating the model variant.

Thanks chaps - I stand corrected and will bow to your evidently superior knowledge
Really enjoying this thread; while I like to think I know some AA guns inside out, there seems to be precious little info on the 100 Series rifles and this thread certainly contains more than I've found elsewhere.
Dale; can you tell me anything about the finish on the NJR breech blocks please? I've owned examples finished in both silver matte and black gloss anodising; I assumed the silver was present on earlier guns and later changed to black; although serial numbers don't seem to back this up. Might the action block colour have been an option too?
