...3 stripes is a bit older than the coil with 4 stripes...

Thanks for that info, I wanted to identify that.

The code number mentioned, I got from a page of a very old printed SM of 3301/00, most of the parts mentioned there, mechanical and electronic, have the numbers 4822...as a header. The peculiar thing, is that most of the electronic parts, R, C and S (inductance) in the SM are mentioned by a code number 4822...without any value...you have to check the schematic, which is not easy to read, except of the S values which are not mentioned!. The inductance measured at the setting I found both, was 4-5mH, since it is a variable one.
