I think there is a set of what looks to be new old stock datsun B10 Clear Parker lenses listed on ebay.
I am 99% sure, but if anyone wants to confirm with the seller the Lenses should read...
 
SAE PD66 EW6030L MADE IN JAPAN
SAE PD66 EW6030R MADE IN JAPAN
 
 
 
The listing states local pickup only.
I thought this might be of interest to someone in the area.
