Genuine Vintage Suzuki  Spanners  22 mm Ring, 10, 12 open ended Spanner
Only Suzuki I ever owned was a B120 about 40 years ago, so this is probably from then.
The ring and the open ended are marked with the Suzuki logo but the third "C" spanner has no markings so Im not sure it belongs,,, looks more like an old push bike bottom bracket wrench. I have a similar "C" wrench to adjust my Honda mono shock, but I think the B120 had three settings and you you just twisted the shock by hand.
