If the Remington's original, you might want to check sold listings of it on the auction site. I don't know if those Queen Barlows with the monolithic aluminum handles are sought after. The patent was for making knives less expensively, which is anomalous behavior for Queen.
Not sure what you mean about queen. They have been selling working man's knives for years at low reasonable prices. Maybe not so much now, but I am not too familiar with their product line and prices since they changed hands.
A few weeks ago, I saw a Queen Barlow with their patented closed back construction for [sorry can't give a price due your and my membership level] at a survival show and it was delrin not bone. Priced way too high in my opinion but the dealer was ready to deal. She heard me mutter to my friend about price, wanted to know what I would pay, but I knew she wouldn't match a price that would have put it in my pocket, so I just told her I didn't want to insult her and we left it at that.
Per the Remington, many patterns were reissued under contract to Cammilus, so it could be newer. I believe those can be identified by a year on the tang (e.g. 1994). The Remington website has a listing of their patterns and IIRC both the original and re-issued ones. Cammilus Remingtons are not rare, but some people are delusional about their price. At the same gun show, I saw the same delrin handled banana trapper priced from [sorry can't give a price, but it varied by a factor of 2] between three dealers. All three were unused and two were new in box, including the cheapest. If it is a Cammilus Remington, the bone ones are significantly rarer and more desirable than the delrin. Some of the bone ones have sterling silver shields and they are priced higher. However one dealer told me there is a glut of Remington Camilus and that's why the price is so variable. His was priced high so he could come down for people who don't know...
Henckels for some reason is desireable. The same person who had the Queen had a good old Henkels in stag and she would not bargain and the price was too high for a used/buffed knife...but the stag was sweet.
Take a good look at the gold colored gentleman's knife. Some have 10-14K gold covers. Often the 10K mark is hidden on the inside of the bail.
