The front panel is very very similar to my circa ~1980 Japanese Kaise SK-160.
I got it as a gift from a family friend for my 21st.
The rotary dial markings are almost an exact match however the case in mine has 4mm banana jacks exclusively.
Mine also uses 2 batteries for the R ranges, a 1.5V cell and a 15V cell for which you can easily stack five 3V lithium cells and a couple of spacers all covered in heat shrink as a substitute as the 15V cells are getting hard to find these days for a reasonable price.
Other features of mine, DC current to 12A (dedicated jack), AC current 0-12A (one range), Capacitance (AC source required), Decibels, DC to just 3KV, 30uA and 0.3V ranges (dedicated jack).
Good meter, look after it.
PS, these are NOT fused and don't have the modern safety devices, GDT's, MOV's etc so wise to restrict use to low energy circuits.
