For my personal educational purpose, I need old version (obselete) of the following ASME Boiler and Pressure Vessel Codes:
ASME Sec. I, IV, V, VIII Div.1, IX and B31.1

I understand that most companies discard them when new ones are released. If you have them and want to discard, at your wish you may donate them to me, which would be quite helpful for my study. I will pay for shipping expenses. I can also pay any small sum to cover any expense.

I would greatly appreciate your generosity.

Thanks
