Nikon SP Variations

A relatively undocumented part of Nikon Rangefinder collecting is Nikon SP variations.  Very early ones (probably the first 300) really are different.  Of course the most famous SP variations are the switchover from cloth to titanium shutter curtains, and the optional  Black finish rather than chrome.

Very Early Nikon SP (aprox the first 300)

• Brighter Rangefinder Patch than later production
• Machined rather than stamped advance lever
• Thicker 35mm viewfinder frameline
• Four patents listed on inside of back.  Later cameras have either 5 or 6 patents listed
• "Nippon Kogaku Tokyo" lightly engraved compared to later cameras
• Slightly coarser knurling on shutter guard than later cameras
• Advance lever cap has slightly lighter concentric rings
• Strap lugs slightly different shape
• ASA dial on bottom is RED from  10-50,   WHITE from 50-400.  Later cameras have RED 10-32 and WHITE 50-400.
• PC connector collar slightly coarser rings

I am not sure how long each of these variations lasted, but I would guess that variations 1-3 above were the first to go.

Very Late SP's have Nikon F features: identical advance levers, advance lever caps,  shutter release guards, self timers, shutter speed dials, and titanium shutter curtains.
