Grandmother's sewing machine

The sewing machine, with which grandmother sewed even coats and furs. We don't understand the technical condition because we don't sew ourselves. There is a shuttle. The thread is still threaded, suggesting it was in working order many years ago. The sewing machine has been untouched for many years in warm rooms.

It is assumed that it should be taken for maintenance by a specialist because dust has accumulated. Heavy. Must be collected by yourself.
