Hey
Hi These adapters are in great condition.
Do you know if they are compatible with 16 mm film?
I have an adapter that I can throw in for free that will make it compatible.
Maybe they may work for some of my projects.  Do you think there is some room to negotiate?
What did you have in mind?
$30 ?
I can't go that low.  Do you have an old men's watch that you can add to the $30?
yes, I have a vintage men's timex. 
How old is it?
35 years..
Timexes aren't the greatest.  I am willing to take $40 & the watch for the adapters.
I would only do 30 with the watch or I could do 40 cash but no watch included.
I will take $40.
alright, deal
thanks
