The Neal's list this salt mold design as the SN-1. The SN-1 mold series lists the available colors as Clear and Plentiful,Medium Amber and Scarce,Dark Amber and Scarce and Cobalt Blue and Scarce. I own two of the SN-1 series salts. The first one in my collection is in a very dark Cobalt Blue and as stated above is listed as scarce. The base has a 28 point sun burst. This mold in all of the variants has a side which is a quarter inch higher then the other when viewed straight on. All of the Stag Horn series variants were manufactured at the Boston and Sandwich Glass Company between 1826 and 1835.
This is the clear version of the SN-1 which the Neals list as Plentiful. The difference on each of the variants from mold to mold is the base which is always a sunburst pattern but each variant has differing amounts of rays which easily tell them apart.
SN-1B is listed in the following colors. Opaque Clam broth which is rare,Light amber also rare,Blue tinted which is rare and Cobalt Blue which is Rare. Again the Boston and Sandwich Glass Company is the manufacturer. The salt in my collection is more of a moon stone color then Clam Broth. The base on the SN-1B has 32 rays in the sun burst. It is quite rare as I have never seen another this color and it may be a one of a kind.
This is the Variant found most often. This mold was made in Dark Amber and is listed as scarce,Medium Amber which is listed also as scarce and Clear which is listed as plentiful by the Neals. This one in my collection is the Clear variant. The base has a 16 point sun burst on it.
The Neal's list this salt mold design as the SN-1D.This is determioned by The base which has a 23 point sun burst.The SN-1 mold series lists Dull amber as the only available color for this variant.I would say that the color on mine is more of a bright amber. Either way it is a very rare color in the Lacy Salt collecting of variants.
