Help Identifying copper and aluminum in older breaker box

First: Thank you for your time in advanced.

House is a 1969 marlette mobile home. Previous owner said wiring was redone. Now it's time to sell and need to tell potential buyer if house wiring is aluminum or copper.

Is it possible what I am seeing is a mixture of aluminum wiring and updated copper wiring ?
Photos are attached. Thanks again!

I see at least one white aluminum conductor on the bus bar. It has the dull silver color.

The receptacle closeups show copper.

I think I see 4 white aluminum conductors on the neutral bus. The wiring is definitely not all copper.

Theres no exposed wire on the ungrounded conductors in the panel photos but I see some aluminum grounded conductors on that busbar too. If that was mine, I would be very concerned about how the splices are made.

Looks like your going to have to check the box on the disclosure that says you have AL wiring... good luck.

Your unit must be one of the last in the line to have aluminum wiring as it was stopped being used in mobile homes around 1969-1970.
