I highly suggest you put some reinforcement on the inside of the tube if you use the finder holes. Ask your hardware store about metal plumbing strap. You can also bend a regular washer to fit the curve. A fender washer is an excellent choice. I've seen many an RV-6 bakelite tube give way in the finder bracket area. The finder is the easiest thing to bump, hit, stress, or just accidently obliterate. A larger supporting surface on the inside for the bolt is not a small help. It's huge.
Here's a picture of two tubes I have here. Notice the typical cracks on the finder holes. These are typical, without abuse. These cracks are not on the focuser holes or spider vane holes on these tubes. I've seen a lot more besides these.

This adapter plate is a flat deck you can mount whatever you want to it (like finder rings) and it will install on a Telrad base.
You can then mount the Telrad base on your scope with the double back foam tape and have interchangeable finders.
To remove a Telrad base from your scope you can saw through the double back foam mounting tape with dental floss or heat the base with a hair dryer to soften the bond and pull it off.
I like the Telrad reflex sight it is a very fast finder. Be sure and get or make a dew shield for it.
I must admit that I do not use a Telrad on my classic scopes. That is soon to change though because it is a excellent sight.

Well te regular telrad mounts with foam tape right? If I ever do want to take it off, how hard is it to remove? Also, I thouhght more about the finder and thought, well there already is a place in the tube where 2 holes have been drilled, so when I make the mounting rings, I could put the holes like right there. I don't want to ruin the classic feel to the scope though
Telrad tape is easy to remove. Razor blade and a little bit of solvent, like alcohol or paint thinner.
Hey, while it's a "classic", do you want it to be a usable scope or a museum piece?

Love your scale model :-)
on my c-5 I use weatherstripping foam tape (adhesive on one side) on the rails of the quikfinder base, and then zip ties around the tube over the front and back of the base. Works fine. Or, you can use big rubber bands, till you find the right place.

Of course, I was a lot more limber at age ten than I am now.

1. You can add zip ties together; they don't have to be super long.
2. You may be able to zip tie a telrad to the existing finder. Won't look that good but may work pretty well.

Zip ties are another mounting option. They can hold a Telrad base quite firmly if you can find them long enough to fit round the tube. I have used them on a 5 inch diameter tube to hold a telrad base. You can get black ones about 3/8 inch wide at Lowes.
You don't need to find zip ties long enough; just string them together: male end of #1 goes in female end of #2, etc.

With all the good advice on how to mount a finder without scratching your tube, you needn't worry about causing any damage. As far as being inauthentic in mounting a right-angle finder, don't worry. Anything removable that works for you and keeps you comfortable is fair game. Adding a right-angle finder is something a customizer might have done back in the day anyway.
Perhaps you could find a vintage right-angle finder. I was thrilled to find a vintage, orange University Optics 8x50 right-angle finder for one of my orange C8s. The other may get a blue Meade 9x50 of the similar vintage (slightly newer), or even just a modern Orion. No way will the original 6x30 straight-through remain, other than in safekeeping for posterity. My neck says, "No!"
If you can use a straight-through briefly without discomfort, try sighting down the tube prior to sighting with the finder. With a little practice, you may be able to get the object into the finder first try nearly every time. Then, tweak it into the crosshairs, and you're done.

So I like to have things matching, so I think I might paint the finder I made with the same color and add that same black trim to the front of it.
Still have to make a plate that will fit the existing holes and make rings to attach the finder, so I've definitely got some things to do!

Another trick to point the scope at a bright star that is near the object you wantt to observing and make sure the circles read the correct RA and DEC of that star the move the scope to cooridinates of the object you want to observe.
That is exactly how I use mine.
