Thank you for all the suggestions and apologies for stating that "the mudguards" had the holes - it is only the rear one that has the holes for a skirt guard.
The Gloria frame lugs are not identical to those on my frame but the top mounted bolt is identical. The bolt on the Gloria usually has a capital letter G on the end of the nut - mine is plain.
If the Magistroni headset on my frame didn't have a plain circular lock nut, it would have had a lamp bracket of some sort, with an L or not.
I can't find out whether the early [pre ww2] Legnano frames had the L lamp bracket before the warrior type and I know that other frame manufacturers were associated with Legnano, as part of a group of companies.
If some kind person could explain to me in simple language [me being a simple computer person], how to put photographs from "My PIctures" on my PC on to here, I'll have a go. Or can someone do it for me please ?
Thank you for all your interest and help.
