Great gun, wish I owned one. I sold my 870 collection years ago to someone who is in love with them or sold them to someone who is in love with them. I still own a 1970s Skeet that is kind of a cult gun.
I paid around $425 for one about 6 months ago. That is the give or take price on gun broker.
Remington made a number of grades, TA, TB, TC and some others.
From what I read on the interweb, TA was lower grade, TB had better wood and TC had better wood and a little bit different barrels.
Mine is in very good shape, but shoots a little flat compared to my Y Model 12.
I briefly thought about adding an adjustable comb, but it doesn't make sense to me to add $200 to a $400 gun and get a $500 gun.
I will probably just add stick on pad or let it roost in the safe.
The T stands for trap model, and the B stands for what Remington called B grade wood, which was typically fancier grain that the standard grade of wood.
Some of the TB stocks had quite a bit fancier wood. TB's still had press checkering on the wood.
The TC model has a little fancier yet wood, TC's had cut checkering.
I have seen them sell from 400 to 600 on Gunbroker over the last several months depending on condition. I have a TB and an 870 Competition and love them both. They will smoke targets when I do my part. I really think they are great guns for the money. Enjoy and shoot well.
I recently bought back a very nice 870 TB in 99% condition with a Monte Carlo stock paying $500 to get it back. Fair deal for both seller and buyer. Regards, Ed. FWIW, pristine 870 TBs with MC stocks are kinda hard to find.
It's worth as much as you're willing to pay. I had one a few years ago with really nice wood I paid about $550 for. Sold it like an idiot. Just got another with nice wood for $450. Best trap gun for the money IMO. Shoots great and looks even better.
