Ron's got it, I believe.

Could have been displayed, not only in Philco dealerships, but
department stores and such, where there were many brands so
as not to get PRR&T "display" property mixed in with store inventory.

Probably sold off once that model year expired and new models showed up on a yearly basis, depending on market locations, turnover, etc.

I'd not seen that before myself. Neat!
