All About Pocket Knives

I bought this off eBay. Appears to be a nice knife but can’t really match it to a specific model vintage model per the Stewart and Ritchie book “Remington knives: Past and Present”

Key points: Teardrop 3 5/8 inches overall closed, with a clip and pen blades both stamped Remington, bone scales, straight bolsters and crest shield. No Remington blade etch or model number still visible

I’m attaching some pics

Thanks

Looks like a R183 to me?
Nice knife

Thanks!....I was waffling btw the R153 and R183 on the length!
