Vintage multimeter test leads - where to find?

(1/2) > >>

Peabody:
I have  a Monarch MT-222 analog multimeter.  Mind you - this is a genuine Monarch MT-222, not some cheap imitation.  Two jewels!  Anyway, over the years I've had to rework the DUT end of the leads several times, but would really like to just get new leads.  The problem is that the meter ends of the leads are very small pins.  They are about 1/16 inch, a little less than 2mm.  Everything I see online is either shrouded, or banana plug, and much bigger.  Does anyone know where I might find the right leads, and what would be the correct term to search for? This meter dates back at least to the 70's, and is no longer my primary analog meter.  But I would like to restore it to a useful condition, and would rather avoid splicing if I can.  The AA says best if used before 2002, so I probably will replace that, although at 1.48V it's just broken in.  But otherwise I just need to get leads that work.

Are they like these? https://www.amazon.com/JFtech-Bullet-Banana-Connector-Female/dp/B08F1XYPWF

I used connectors of this type to connect small brushless motors to the speed controller in RC planes.

Probemaster has these with 0.080" pins.  Does that work?

No-load voltage? Then it’s already going bad. Given the age, leakage is a likely outcome, and given how cheap AA batteries are, just replace them.

Peabody:
I think the Probemaster leads would work.  But at $22 plus shipping, I could just buy a new meter as good as this one.  So I guess I'll rework the ones I've got, and try to implement some better strain relief.

As for the battery, I think I will use this meter for current and voltage, mainly current, so it won't need a battery at all.
