Cooke Speed Panchro S2 40mm T2.3 Prime

It is important to acknowledge however for anyone not familiar with these lenses is that they are 40+ year old glass (in modern housings) so obviously they have their own quirks (which is the magic of them).  For instance the glass in all the 75mm lenses from this series have all yellowed with age, so you need to adjust white balance or filter appropriately.
