Ceiling tile

I purchased an older mobile home and it has some damaged ceiling tiles.

Does anyone know where I can buy some replacement tiles? The tiles are 16" wide and about 14 feet long. So far, I have been told that they no longer exist. There must be someone out there that has salvaged tiles from a tare down.

but what i have done is taken 3/8" drywall and re skinned the ceiling in that room. Have taken from one bedroom and used thru-out home for replacemant and then done a drywall lid in the one bedroom also.
