Identify my Remington Double Deringer

[Lone Rider]

I am trying to find the origin date of my Remington Double Deringer Over/Under.
According to the markings, it is a type II, model nr.3, manufactured from 1888 to 1911 in 80.000 items. My pistol has serial number 955.
It seems it is impossible to give a date for Remington weapons according to their serial number before 1921.
As all numbers are always with 3 digits, I have read that there are collectors who are looking for weapons having the same number. This makes me suppose that, once at 999, numbers started again as from 001. Since there have been 80.000. That would make 80 pistols with the same number…
There are several types of markings as well as you can notice on the picture (see link :

Please note that mine is the 4th from the top.
I wonder if it is not this way we have to search to attribute the date of manufacturing of these weapons : were the multiple makings attributed simultaneously or maybe was the matrix changed only when the previous one was used, which would start to give a clue on the production period.
Could someone help me ?

Only some of them are difficult.
Type I Model I - can be based on quantity/serial there's a small window. (also 3 "major" variations, backwards print doesn't count )
Type I Mode II - they repeated the batch no's twice - nope
Type II Model III - Shortlines only - other 5 variants - nope
Type III Model IV - (UMC) yep serial no's and production no's even before date stamping although late numbering got weird date stamping was present.
Type III Model V - (monoblock) date stamp (and serial)

Actually they are not 3 digits, they started at 1 and continued to 9999 and then repeated, with exception of the shortline (1st variant) which only made it to slightly over 3,000 and didn't repeat so it could be considered a serial no

So Douglas Drummond's new book should be arriving hopefully soon and he may shed more light on this subject but I'm unaware that even the order of the Type II's variants (other then the Shortline) much less the quantity of each is known
