Hi Creanie, and welcome to the forum! I have a Bambi II also & have never seen a manual. One time a member here offered me a copy, but I never heard back again from him.
As far as a parts catalog, one of those doesn't exist. You can find a lot of parts you may need at Vintage Trailer Supply.
Congratulations on your new trailer & pictures are a must! What number trailer is yours on the serial number? Pa Bambi has number 2, and I have number 3, so it would be so cool if you have number 1 or number 4!!!!!
