Jennings Sun Chief Questions

[Truchaos]

I have a Jennings Sun Chief which I'm restoring. I have a few questions for the experts here. Judging from the internal label, it's a Tic-Tac-Toe model with no sticker on the jackpot glass, and the case date shows 1949. I've very interested in restoring to it's original state.

1) Should the back cover (metal) have the large J stamped in the middle like other models? This one does not.
2) Should the key be a regular toothed key mechanism or the tubular type I've seen in other models?
3) The lock is missing from the cash box, should it also be a toothed style key?

Thanks for any help you can provide

You may receive additional comments but will offer my thoughts. Primarily based on my Jennings Sweepstake with serial in 19x,xxx late forties range. Definitely should have the "J" back door. And both back door and cash box locks (locks are same physical size) are the later tubular key type.

Hope that is of assistance. Flip
