An Old Ladder

Today my gardener took out a ladder to cut the old leaves of palm trees in my house.
When I saw the ladder, I said to myself, oh I already have a good ladder that I bought long long time ago.
You can see how rusty the steel rods are at the base from the photos below.
How can I be so forgetful, must be my age!

It's a knock down type and each part can be bought separately, should be very applicable for bird house.
