I have a Jennings "Mints of Quality" that I recently re-installed the delay pay mechanism on.

However once I did this, I found that the cash box didn't clear and fit under the payout chute and "holding area." The box I have looks quite old but I suspected it might now be for that machine since the pull-out tab is on the side and not the end where you'd pull it out.
I don't know enough about these machines to know if this is a standard size for machines with the delay pay, so if someone knows, let me know.
And I will have the other cash box so I'm hoping I can just trade this one for the proper box.
