EPSG:3838 Pulkovo 1942(58) / 3-degree Gauss-Kruger zone 4
Projected system (Transverse Mercator) in use: Europe - 10.5°E to 13.5°E onshore by country. The full definition below, and conversion in one click.
EPSG publishes no simple transformation to WGS 84 for this datum: conversion works on the ellipsoid alone and can be off by tens of metres.
