Important info about my lenses:

All of my lenses are professionally checked, cleaned, lubricated, adjusted, serviced and throughly tested optically and mechanically.
This is an expensive, time consuming job.

These vintage manual lenses are decades old and ALL of them require service, most sellers wouldn't even notice that - in better case they just clean external surfaces, maybe put some adapter on and put out the lens for sale cheaply.

So you might find the same lens cheaper somewhere on Ebay but there will be a huge chance that you would get not serviced mediocre performing copy with degrading quality and hidden faults.

My prices include servicing and testing job so you are buyng quality tested product, not just some dusty flea market find!
