Chiyoko Rokkor 1:3.5 50mm LTM Lens #1100008

[Rangefinder Man]

Hello All
I have come across this Chiyoko Rokkor 50mm (not 5cm) f3.5 LTM lens, but can’t seem to find any info on it, so maybe a prototype lens. Can anyone help?

I checked a number of sources and found nothing, post some pictures please, I wonder if it's a transplant.

The Japanese auction has finished now and they must have been prototype lenses, as it sold for USD$7862! Some hard core collectors on this auction.

Nice auction title
"Junk MINOLTA Minolta lens camera parts!"
#8, 17, 20, & 21 of a lens that seems to not have been released, cool stuff.

I just posted a query about a Minolta 50/3.5 Macro lens with LTM. Wondering if this was a prototype for this series of lenses, as the ser# range is the same, starting with 110xxxx?
Mine is in the 300’s, so very early in 1958?
