I have now fully reassembled the interior of the 240, having fixed all of the electrical gremlins and in preparation for its holiday to Berry.
The picture below shows what I found on my journey through the interior/dash that were loose in the cabin or under the carpets. The exception is 7... I took those out and I just can't remember where from... everything went back together without needing them, which is worrying me!
I have no idea if all of the rest are even from the Volvo. Some I recognise (like 1) as being of Volvo origin, but not sure where specifically they go.
The coin is a $2 for scale.
Most correct answers wins a beer :D
