1957 models 
1957, 1958 & 1959
Glastrons all have fins in the back and look a lot alike. The key to telling
them apart is looking at them from the side. The finned area of the '57
has a tall area of the fin that is colored as the upper deck. See the 1957
section of the site for more info. and about the metal sidespears and
emblems.
Above is a '58 Glastron.
You can see how the colored upper deck area of the rear fin is not as tall
as
the '57. A large silver
side panel is new and reaches forward past the center of the boat and comes
to a point in the front. At the rear most part of the fins the colored
part comes to a point and hangs over past the transom. Almost every '58
Glastron you come across will be of this design. The Surflite, Seaflite,
Inboard and Fireflite will have this. The Skiflite is slightly different
and there is also a canoe and a fishing boat. See the 1958
section of the site to see all models.
Above is a '59 Seaflite.
Like the '58s, most of the '59 models had the same basic hull styling.
Very little was changed
for 1959. The most noticable change is the new treatment of the silver
side panel.
The forward part of the
panel now stops behind the midpoint of the hull at a straight angled cast
piece.
The forward pointing molded
in ''C'' shape can still be seen forward of the new cast piece, but it
is now hull color. See the 1959
section of the site for more information.
1957, 1958 & 1959 Glastrons all had these emblems on the hull with the exception of some '57 models which had mylar stickers with the same logo. The boat logos were chrome plated and had a wide band underlining the letters. This band contains STANDARD GLASS PRODUCTS INC., AUSTIN TEX.
1957 emblem with
chrome plating gone.
1959 emblem with
letter ''l'' gone but showing nice original chrome plating.
Some came with a sticker
below the emblem like the '59 emblem above with the broken off ''l''.
The sticker below the emblem
reads: DESIGN PATENT PENDING
The following pictures show the location of the paper I.D. tag on '57 models which is underneath the rear deck and faces downward toward the bilge.

Although the tags were covered with clear resin, the areas that were filled in probably by hand with a pen are faded and can't be read. The printed part of the tag reads:
STANDARD GLASS PRODUCTS INC.

GLASTRON
1958 through 1962 Glastrons
seem to have had serial numbers stamped into the rubrail at the rear of
the boat. See the section on deciphering serial numbers at the end of the
next page.
