Identifying Sugino bottom bracket

Wondering if there is anyway to identify a Sugino loose bearing bottom bracket without removing it from the frame?

The cups looks like these and I get the feeling the spindle is ISO/NJS but I guess I won’t know until I pull it out. (Time poor at the moment)

If its NJS, the spindle will be stamped and the cups should also be stamped NJS.

The above picture is to the contrary. NJS stamped spindle, no stamping on the cups.
The Sugino 75 cups are panto’d to say Sugino 75 from the ones I’ve seen.
Guess the BB is coming out over the weekend then.

Every other NJS BB I’ve seen is stamped on the cups.

One of my mate’s Sugino 75 BB is not NJS stamped on the cups. Bought new from tracksupermarket 3 months ago.

i am palping a sugino 75 bb that is stamped on the spindle but not the cups

I’ve got a Sugino MW-68 bottom bracket and I’m pretty sure the spindle is stamped but the cups aren’t.

Edit: Yes they are.

Without the NJS stamp the bottom bracket is useless- throw it away.

Maybe it’s just the Hatta Swan BB’s that are stamped.

No, I’m stupid. The cups are NJS stamped.

It was so good, I posted twice.

yeah same

Where are they stamped ? Pics or they arnt!!!

Nice work, thanks.
The BB cups I have look like these but are not stamped.
However spindle is an SR that is 111mm long and symmetrical so I’m guessing it is a Campy Record compatible spindle.

So it’s ISO taper?

It certainly doesn’t look like JIS and I’ve never found a JIS spindle 111mm long.
I’m measuring this with a set of Mitutoyo calipers.

This looks like the spindle I have :-
