AJ,
Thanks for the extra pictures.
As I suspected, it is a loose copy of the Remington , but definitely not the same. Not a Flobert either. Flobert breechblocks are held closed strictly by the strength of the hammer spring. Yours is interlocked by the hammer like the Remington.
I have found several similar target pistols (or as the old Adolf Frank catalog called them "Practice Pistols for Crack Shots"
, but can't find your exact one. One somewhat unusual feature is the .44 cal. Most of this type of pistol I have seen are in the smaller chamberings. (.22 -.32) I would guess it was made sometime around 1900, give or take 10 or so years.
I think this is a fairly decent quality gun and you got a really good price on it.
(BTW, Your picture taking skills are getting much better.
