Appears to me to be the original brown leatherette on the SE version of the K1000. My daughter took one to New Mexico to shoot landscape about a decade ago but she then went over to the dark side in 2004 (Canon). IIRC there weas a small gold sticker on the bottom marked "Hong Kong," but not all SE's were made there. You should have a 45' split-image VF, the principal benefit of the SE version (and a rare and useful feature).
Here is a link to the K1000 Serial Number database thtead originally compiled by Ole from members responses.
You can use this to place your new camera in the approximate time sequence of its manufactuere.
Here is where you can view the data and add the information for your specific camera
We will appreciate you completing the infomration and forwarding it to the database keeper!! TYVM
