My Ideal Catalog No. 26 (post 1907, pre 1920) shows a number of tools similar to the ones shown in the pictures.
I don't think it's a stretch to say that they are related.
Regarding the catalog, I believe it's actually between 1907 (introducing date for the .44 S&W Special) and 1912 (the date that Remington and UMC joined), as the .44 Special is listed, while the UMC and Remington ads indicate that they are separate and independent.
Interestingly, there's also an ad in the back for Maxim silencers.
