I picked these up today at our local club spring swap meet, seller said he bought them online off of a Japanese auction site at some point in the past.  They have spent time in a car as there are a few scuffs on the leather and a bit of chipped paint, also the mirror is missing the original convex mirror.  I have found a few pics online that look similar to the competition wheel but almost nothing on the mirror.

Can anyone fill in the blanks for me?

Thanks

 

The mirror is a (relatively) recent re-pop of the factory Race Option interior mirror. I have one in my KPGC10.

Here's an original in use:

 

 

I did some more hunting and I'm thinking the steering wheel might be one of the first wheels or the reissued ones by Nissan for NISMO's 10th anniversary produced late 80s - early 90s that came wrapped in leather. https://jdm-car-parts.com/products/competition-steering-wheel-for-vintage-datsun-nissan-genuine-nos?variant=1231461416

All the newer steering wheels I found have a composite urethane hand grip, https://jdm-car-parts.com/products/datsun-competition-steering-wheel-for-datsun-240z-260z-280z-510?variant=13657908543597

Also, the rear view mirror has a notch stamped into the housing and backing plate for the pivot ball that lends itself for a right hand driving position whereas the newer replica versions don't have that and are more universal.  https://jdm-car-parts.com/products/datsun-competition-racing-mirror-reproduction-for-datsun-240z-260z-280z-skyline?variant=774787501

I've been told the original competition mirrors had a convex mirror in them but I haven't found any confirmation on that yet, the newer replicas have a thin flat glass mirror.

Where did you get "wrapped in leather" from? The genuine steering wheels - whether early 1970s originals or NISMO Anniversary re-pops - were all manufactured by Izumi for Nissan and were made from a skinned Urethane material with moulded-in faux stitching detail. They were never leather.

Recent (Chinese-made) copies are another matter.

Honestly, do those screws and rivets look like they are 50+ years old to you?

As with all vintage items, provenance is key.
