If you're looking to actually "restore" that shotgun, you will want factory wood so I would call Remington to see what they can offer. If I was buying a nice older restored piece, all-factory or at least all factory-identical parts would be a requirement.
E-bay and Gun Broker have different wood sets on there often. In the past I have purchased both a original early 50's TC set and a red - white - blue laminated set that was unfinished.
Still waiting to finish and install the laminated set. Numrich Gun Parts Corp. also has many wood sets.
Enhanced receivers were made for a short time in the late 90's/early 2000's.
Some machine made engraving all over the receiver that to my eye looked very gaudy.
I won a 870 field gun in a raffle with the enhanced treatment and it was traded not long after.
I have a brand new stock and fore end that came off an 870 Classic trap. The stock is Monte Carlo. It has some nice "spiderwebbing" in it. If you think you are interested, pm me and we can discuss it and I will take some pics, but my phone camera isn't the best.
