SML models were available as a straight Bb soprano, Eb alto, Bb tenor and Eb baritone. Eb baritones with low A keywork were found only on the King Marigaux stencils, it seems.

• As far as I know, SML never produced C saxophones or curved sopranos. By the 1930's, the saxophone craze that started in the US in the 1920's and produced these horns had long since died out.
• As far as I know, SML never produced sopranino, bass or contrabass horns, or experimented with unusual saxophone designs (e.g. a straight tenor) or odd pitches (e.g. an A soprano).
• As far as I have seen, all SML horns are low pitch, A=440hz. By the 1930's, the only company that was producing high pitch horns in quantity was Conn.

Models were available in:

• Lacquer (starting with the Model 49).
• Gold plate (burnished and satin). This plating choice may not have been available for the Gold Medal horns.
• Silver plate in matte or "sandblast" (burnished) finish. Some silver plated horns were UNENGRAVED, except for the SML logo.
• Nickel plate (relatively rare).
• Lacquer w/nickle plated keys (i.e. "Two-Tone"). This finish probably started with the Rev. C horns.
• Silver plate with gold highlights. This combination may only have been available on the Rev. A horns.
• There was an option to get a solid-silver neck for some of the horns before the Gold Medal series.
• There may have been some Marigaux horns produced with a sterling silver neck and bell.

The baritone was probably not introduced until the Rev. D era. The soprano and baritone were unchanged in design hereafter.

I've recently been getting a lot of odd information about the desing of SML baris:

• Some models may have wire keyguards (which looks really odd)
• Some models do have adjustable felts on the keyguards

I think it's very safe to say that the baritones may have been custom made and SML told buyers that they could get a variety of features.

In any event, please note that SML said that the best bore for their horns was the one introduced with the Gold Medal -- and that the Rev. D and Gold Medal have different bores.

Click on the below pictures to go to the feature page for each model.

- Missing adjustable bell key felts (#20).
- Elaborate engraving (#16) was available as a custom option. Bell lip engraving was not available. (See the silver 25xxx alto at left that has virtually no engraving.)
- SML horns have different engraving styles after 26xxx
- Marigaux horns have different engraving styles after s/n 25xxx
- Rolled tone holes were not available (#19).
- King Marigaux models may have had an option for sterling neck and bell.

There have been some notes from owners of late horns that the adjustment screws don't work at all.

====

- Sopranos and baritones had most of the features of the "Rev. D" models (see notes above).
- Sopranos and baritones did not have "Gold Medal" engraved on their bells and may not have ever had engraving on the bell lip (#16).
- Sopranos did not have the neck lock (#4).
- Sopranos never had rolled tone holes (#19).
- Both baritone and soprano models did not have clothes guards (#15).
- Sopranos were lacking in all set screw adjustments (#12, 14 & 20).
- Sopranos did not have removeable keyguards (#17).
- Baritones did not have G# (#12) or Bb (#14) adjustment screws.

====

- Some horns started featuring altissimo F# keys. This may be a custom feature that could be ordered after s/n 20xxx, but I have only seen it on Marigaux horns after s/n 25xxx. It may not have been available for the soprano or baritone models.

- Bell lip engraving (#16) was not available, but otherwise the engraving paralleled that of the Gold Medal models.
- Rocking, adjustable thumbrest (#23) was not available on all models.
- Not all horns featured adjustable bell key felts (#20). This appears to have been a randomly added feature.

- Sopranos did not have the neck lock (#4).
- Sopranos never had rolled tone holes (#19).
- Both baritone and soprano models did not have clothes guards (#15).
- Sopranos were lacking in all set screw adjustments (#12, 14 & 20)..

- Adjustable bell key felts (#20) were not standard until s/n 8xxx or so and didn't appear until 78xx at the earliest.
- Clothes guard (#15) was not standard until late in the series, possibly not until s/n 8xxx or so.
- Bell lip engraving (#16) was not available, but otherwise the engraving paralleled that of the Gold Medal models, although not quite as elaborate.
- Rocking, adjustable thumbrest (#23) was not available.

- Sopranos were lacking in all set screw adjustments (#12, 14 & 20).

- Some models had a sterling silver neck. As far as I have been able to determine, this feature may have continued to the end of SML manufacture, but I have not seen this feature on Gold Medal horns.

Please note that there are several versions of the Super horns. Check the page for details.

- Neck lock (#1) was not available.
- Different octave key mechanism (#2).

- Removable key keyguards (#17) were available only on models with sheet metal keyguards (say, after s/n 7xxx or so)
- Rocking, adjustable thumbrest (#23) was not available.

- It is possible there are no Super baritones or sopranos.

The Standard was introduced as a low-cost alternative to the "pro" SML and used the older model's tooling, similar to what Buescher did with their Elkhart line. (i.e. if you got a Standard with a serial number of 16123 -- a Gold Medal-era serial number -- it'd have most of the features of a Rev. D horn).

All Standard horns have "Standard" engraved on their bells.

It is probable that there are no Standard sopranos or baritones.

There are at least two versions of this horn:

- "The Coleman Hawkins Special": this horn is patterned after the Rev. A horns and has left-hand-side bell keys (and slightly different keyguards).
- "SML Coleman Hawkins": this horn is patterned after the Rev. B horns and has right-hand-side bell keys.

Please note that in both instances, these horns have considerably different engraving than standard Rev A or B horns, they have larger bells (especially the tenor) and they have rolled tone holes.

It is possible that there are no Coleman Hawkins baritones or sopranos.
