Welcome to the forum! I'm no expert, but I did own a 62 Bambi at one time.
Would this happen to be the Bambi I saw in Vancouver a few weeks ago at the Mushroom Festival? I didn't get a close look at it at the time.
I think it should have electric brakes. If it does not, and it has the original axle, you might want to consider getting it replaced with a new axle with complete new brakes. New running gear is a wonderful thing. I had mine done at RV Pro in Hazel Dell in 2004.
If you can get anything that goes with it originally, do so! You will not regret it. I'd rather haul something to the dump later than wish I had grabbed it when I had the chance. Yes, some of that stuff is valuable to restorers.
Vintage Trailer Supply is a great place to look for all those items (door locks, etc). The broken glass should be flat, so you can have it replaced by any glass shop that can cut a piece to fit. VTS will have the weatherstripping you need to put it all back together.
The dent is tricky. You can research it here. I would not trust a car repair shop to touch my trailer
There are Airstream dealers in Milwaukee and Eugene, I would take it to them for an estimate to see if they thought they could pop it out first. As long as the seams next to the dent are still sealed so water can't get in, it's just cosmetic.
Good luck, that's a rare find, and although it's been converted, it can certainly be turned back into a sweet little camper!
