Thank you very much for your info. Where can I find set screws for my 2 green Wheels ?

That does look like the boss used for A. C. Gilbert's production of Meccano. More information is under "Parts" at usmeccano dot com; click on the picture of 19b s. [It looks like I cannot post a link to the page.] The screw used is #6-32 with an outside diameter of 0.138" (3.505 mm) and 32 threads per inch (0.794 mm pitch). The hole should be around 0.1065" (2.70 mm) in diameter.
