These are brand new NOS Delco Harrison thermostats. Note from the picture this is how they were to look before they changed them all up to the new cheaper style.
3 Delco 146P 160 degree
1 Delco 148P 180 degree
1 Delco 149PH 195 degree
The H on the 149 stands for High Temp as the reg 149P was only 190 degree.
A great assortment of heat ranges for your vintage auto.
