Can someone help identify the backsprings on this R100A knife?

[dodgin2]

This old Remington R100A has covered back springs with PATENT PENDING on the cover. Can anyone explain this to me? Thanks, Ben

Your knife is the "standard dollar knife " Remington made 2 knives with a covered back spring that I know of. This one and a version of the R3333 scout knife.

Your knife at one time had an etch like this.

Queen made barlows like that, probably more with covered backsprings out there as well. I happen to have a R100 A at home that I EDC around the farm, there is a R100 B too I think.

Here is a R105A
The R100B doesn't have covered back springs.
