Cooke Kinic

I have been looking online to find the original use and current value of this Taylor-Hobson Cooke 2in. (50.8mm) f/2.8 Kinic lens. I posted in 'Darkroom Equipment' assuming someone in there might know something but no replies.

Anyone know about this lens, its original usage, possible use with medium format, value?

Thanks,
