Liz,
I've cross-posted this to the clone brands subgroup of Lugnet, where you'll
get people much more knowledgable of the similarities & differences between
Lego and other manufacturers. There are no stupid questions, although
finding the answers may take some research.
The two parts you describe (the 75 slope and the 1x1x5 brick) are made by
Lego. Lego makes several pieces with hollow studs. I don't know if similar
pieces were made by clone makers, although this newsgroup is the place to
find out. In my experience, clone slopes do not have the surface texture of
Lego slopes. The 1x1x5 brick sounds like Lego. It's hard to tell from your
description, but some Lego hollow studs have a tri-bar blocking the inside
stud. See this pic:
http://www.brickshelf.com/cgi-bin/gallery.cgi?i=208855
which shows the completely hollow Lego stud & the barred Lego stud.
Lego has produced pieces that don't have their logo on them. Although the
studs have had a Lego logo on them since the late 1950's, it is only
recently (during the 1990's) that the company has made a point of putting
the word Lego somewhere on most pieces. Specifically, the tiles you mention
do come in earlier versions without the word Lego stamped in the bottom. The
absence of the Lego word or logo is no proof, in-itself, that the piece is
not Lego.
The "labels with a design" are called stickers. Stickers are used alot by
Lego and clones, although the designs on the stickers tend to be different.
The small single-digit & double-digit numbers you are seeing on parts are
what I call mold marks. I'm no expert on plastic manufacturing, but I'm
guessing that the first number is a die number (the giant metal block used
to mold plastic); the second number is the cavity number (each die would
have several cavities, each cavity producing one "piece"). They were
probably used to track down quality issues during production, so they would
have no meaning to us. Such numbers have appeared on bricks since the early
1960's.
The "Patent Pending" is a mark placed on a piece to indicate a patent
application has been filed. Patent Pending bricks appeared in the 1960's &
1970's. You can see the same mark "erased" on some later bricks, indicating
that the Application was resolved. Eventually the mold was changed & the
Patent mark was taken out completely.
For a visual tour of 17 mold variants of the 2x4 Lego brick, including some
of the above variations visit this link:

In the upper right corner there is a big pic & a matching text file
describing the differences shown.
Hope this helps & good luck in your quest,
Clark

| Whilst on the subject of Lego / not Lego, I have a question. I have recently bought at a boot fair a bag of Lego, most appearing to be the same era as the stuff I have from childhood, c 1970's. A fair bit of the Lego is obviously different though. (...) (22 years ago, 22-Jul-02, to lugnet.off-topic.clone-brands)
