The cartridges for Colt's Thuer conversions
Here's a picture  of the Thuer cartridges showing the complete set.
They are, from the left the .44 Army,.36 Navy and.31 Pocket. Not shwon is the .36 Pocket Navy.
Alexander Thuer received patent # 82,258 for his system of converting percussion revolver cylinders to take a front-loading metallic cartridge on September 15, 1868. The purpose for using a front-loading design was to circumvent the 1855 Rollin White bored through cylinder patent that
allowed Smith & Wesson exclusive rights to the rear-loading cylinder revolver. The peculiar nature of the front loading cartridges, coupled with the complicated cylinder arrangement for loading the cartridges and ejecting the fired cases proved to be unpopular; as a result, production of the Thuer conversions was limited.
Norm Flayderman puts the number at about 5000. while R. Bruce McDowell
(A Study of Colt Conversions) believes that the 5000 number is 'grossly exaggerated', based on the limited number of surviving examples.
His reasoning makes sense, as the examples observed tend to be in good condition, indicating that many, if not all, saw little use, so it is not likely that many of them were worn out from use and consequently discarded. Nor is it likely that Colt had intended their 'New Patent Metallic Central Fire Cartridge Revolvers', as they were referred to in advertisements, to be a big seller but, instead, as a stopgap means to use up some of the accumulation of percussion revolver parts
that they had on hand following the Civil War until a better design could be introduced once the Rollin White patent expired in April 1869.
That better design was the Richards conversion which was being perfected by Colt factory employee Charles B. Richards shortly after the Thuer conversions
first went into production. The most common of the Thuer conversion revolvers were the .44 Army models; the least common were the .31 Pocket models.
Of the cartridges, which were produced only until 1870, the least common is the short .36 Pocket Navy that was intended for the Model 1862 Police and
Pocket Navy revolvers.
