As for spiked feet, I have been using a neat trick I got from the Wardsweb site. Walmart sells target arrowheads for a few dollars per package. I can't remember how many are in the package but there is more than you would need for one base. They are black anodized but if you want you can polish them down to a nice silver. Just drill a hold and glue them in and you have some really nice spikes for almost nothing. I've used them on my FPIII and for my Paramount bases as well.

I've done several of these glue-ups and this is what I do: I get a long straight edge and lay all the pieces with the outside edge up and the bottom along the straight edge. Once everything is snugged up, I run long strips of painters tape from end to end. Usually three strips overlapping. I tend to overdue. Then I flip the whole thing over and apply some tightbond (elmers like) wood glue to both inside edges of the base boards. I smooth it all out with my fingers and I have a couple of cotton towels already dampened and ready to clean up. Make sure that both sides of every surface that is to be bonded has some glue on it. Then I just fold it all up and tightly tape the remaining edge. After that, I just wipe off all the excess glue wit the towels and let it all set overnight. I use a sharpened chisel to remove any glue bumps that might occur overnight and finish sanding from there. You should have great results.
My experience with Brass comes from polishing the dress buckle when I was in the service years ago. We took the clear coat off (somehow) just so we could polish the bare brass to a nice shine. This took constant attention. The coating on top was OK but not eye-popping. If you want super shiny you will have to polish it on a regular basis. I, on the other hand, would quickly become a fan of tarnished brass. After all, it has a look all it's own.
