Forward :
Here is for the first time detailed information about the various sizes and Periods of the Six part-Six Piece Snail- Escargot – Referee whistles made by
Samuel Auld,
Auld made Escargots in the 1880s
since about Mid 1880s (Unknown date) up to 1907.
AULD MODELS were made in SIX standard sizes.
See older posts about Auld HERE & HERE
Auld was the maker identified with making and designing the Glasgow Type Escargot – referee type with 6 Part construction, which became known as the Glasgow type, Vs the London type.
Two other makers were making similar SIX part construction ones at the same period, differing in small details, H. A Ward & Peter McDonald.
It may well be that H.A. Ward was the one who invented the whistle construction since some of his stamps point at trying to register a Patent in the USA.
Ward & Auld are of similar construction, while McDonald had his own unique way.
We can divide this type of whistles into two main periods 1880s up to 1889. That is, Pre 1890, More Precisely up to 29 January 1890 when his Registered design Number 143091 was approved.
From this point onward his whistles are stamped with the Rd. number 143091
In 6 lines.
Thus two periods of these namely: Pre 1890 Rd. and Post Rd. Reg. Design.
AULD MODELS
Here are the three known sizes of Pre 1890 and their typical FIVE line stamp;
S. Auld’s
Improved
Call
Maker
Glasgow

He made 6 Sizes of his Registered Design, Post 1890.
The 3 Barrel sizes -side diameter are Small , Medium, & Large
SMALL 16 mm
MEDIUM 19 mm
Large 22mm
There may be a Deviation of one mm.
In 1890 he starts making SIX SIZES, 2 sizes of each of the Small,Medium, & Large
The new models DIFFER IN STAMP , 6 lines and Rd number & SLIGHTLY IN small details such as bubble top – knop and mouth piece curve His post Rd. numbered design
has two size variations of each of the three main Barrel Sizes,
so there are six Sizes sharing three main Barrel sizes each have having
a longer and a shorter ‘BEAK’ (The longer mouth piece part) The large model has a variation of a WIDER BEAK
Here in photo are 5 of the Six sizes, (the Larger 50 mm Beak Small model
not included is in the single Photo)
To sum it up 6 models easy to memorize SIX PARTS & SIX MODEL SIZES :
S / S.L (Small model & Small with longer beak )
M / M.L (Medium & Medium with longer beak )
L / L.L (Large & Large with longer beak)
The smallest is 45 mm to 47 mm depends on the type of top part (Body length excluding top is about 33-4 mm, Side – Barrel diameter is 16-17 mm ) over all length is 45mm- 47 mm, next is 50mm (Not included in the next photo) Two Medium size Barrel and Two Large (22mm Barrel)
