Hello,
nice find, but no HAZET...
looks like a
CADDY RC-101 from
HORY CO., LTD. made in Japan.
Not only by the red color, also the simpler knobs without a metal insert, which cannot hold tool holders or lamps in them. Also simpler ram protection rubbers. Dividers only in one direction possible. No floor pan divider for stabilization and insertion of a stool. Its a later cheap copy / clone of the HAZET Assistent 162N tool trolley I think from the 1980s or 90s. There also other clones, but these are more different.
HAZET has been producing them since 1954 (til today alongside modern and larger tool trolleys) with 1953 patents in Germany, the USA, Canada, Great Britian, Spain, etc - but not secured worldwide in every country - e.g. as Japan or China.
