Minox II ?
The seller claimed it as Minox II, it looks like Minox III to me
But Minox I I made in 1948/49 SN ended with 25642
From 1950 SN started with 25643 was already Minox III
The SN 38052 belongs to Minox III made in later half of 1951, fully two years after Minox II
Further Minox II should have black shutter white dot.
