Curtis Spring & Tumbler Assortment No. 10200.
I did even try to count every little piece. Pictures are part of the description.
Has two keys in the tumbler. One with a write number down and destroy tag.
Case is in good shape just has normal wear and tear scratches but no visible cracks or damage.
Came with a lot of old keys. If you are interested I can post them.
Says for GM side bar type locks from 1967 - 1973.
That’s when GOOD cars were built!
