Oldbiscuit, you’re fantastic! We just found an old Gougler Keyless RD200 Deluxe in our basement this morning, locked with no combo. I’ve been from one site to the next trying to figure out the combo so we can see if it even works with no luck. But your suggestion was exactly right. And, happily, I only had to go as far as “L2” to get the combo to work. Now, any thoughts/suggestions on how much a working RD200 is worth? Thanks again!
