Great thanks for your interest and kind words. (I am sorry for my english writing).
Petroltank is original but I have beaten it up and gave it brand new knee dents. This is in the begining of beating the knee dents. It was a realy hard work.
I also hammered it underneath so it should sitt lower on the frame
Then I took away fliller cap and took it apart so it was only just the cap left. Then I hammered the tank so the hole for filler cap came lower down in tank so it could not be sticking up in profil of the tank, put a cap from a jam jar on the old cap an drilled a hole in it putb in a hose for ventilation and voila it looked old for my eyes.
Before I made the seat I modified the frame so it would be a little more narrow behind the tank, and shortened it.
The seat, or if it is saddle (I dont Know) is made of sheat metal. Hammered in my workshop on the concrete floor to be bent in a small quarter of a ball. Welded together with the part that is the base for the actually saddle. Then I make one more base and dressed that in brown suede, bulted it right throw an in to some small attachment I had welded on the frame of the bike.
Front end is original , I have just taken of the black paint.
This is when i first came up on the lift.
