3 new razors

hello! this afternoon I found in a flea market these three razors. the boxes are not original, there is a bit 'of rust here and there but they look cute.
the first is quite large, with scales and big plastic pins. I do not read engravings, I have no idea what that might be.
the second is from sheffield, but I can hardly read the name without lens ....
the last one has the blade massacred, I read: "paul mill alger", with the coat of a deer. the scales are beautiful to me :)

any advice?
greetings to all
saluti
stefano

the one with black scales is a joseph rodgers. Lots of info on them in this forum.

The last picture there makes brown razor look huge.

hello! thanks for the info, I try to do a search on the forum :)
the big razor blade has a width of about 2 cm (6 \ 8 "?), length 17cm (6.7"), about 5 mm thick (0.2 ")
I will also be blind but I can not read anything on the blade, probably with a nice clean things may appear, I hope!
saluti!
