I have been given an ashtray collected in the early 1960's from the Sentry Motels, location unknown. I was first told it was in Nevada, and had gaming, then told that it could have been from a diner anywhere across the country between NY and LA. I am looking for any information about Sentry Motels and/or the ashtray itself, including value. I would appreciate any help.

Note that the cigarette indentations are in a type of pinwheel formation. Thanks for any help.
