Parts needed for Milbro mod 23 1962

[Grayling]

I need some parts for my June manufactured 1962 mod 23 Milbro .177 serial no 232516 E. Basically I'm short the leather washer at the breech seal and the top of the back sight. I doubt these parts are openly available nowadays, but am hoping someone my have or know a possible source for these parts.
I have had this old airgun in my possession since 1971 when I found it in a bombed house near were my parents still live. This was therefore my first Air rifle. I have stripped, cleaned and cold blued all outer services and polished and relubed all internals. The stock has also been stripped and sanded and is now getting progressive coats of Tru Oil. The whole little package is starting to look really good.
Maybe this little old rifle isn't that collectable but due to its history it means a lot to me. Any help sourcing these parts would be much appreciated .
