These lugs (on my 49/50 Humber) don’t look like the regular Raleigh lugs I am used to seeing - are these normal for this era of frame?



The one above in particular looks different...





This one looks pretty normal but the “mouth” doesn’t seem as deep as what I am used to.
I'm asking just because I was comparing to other frames I have seen and to Kurt's site and these lugs don't match the patterns.
