Hi OF,

I am looking for (very) vintage shoulderless (also called single shoulder) spring bars as shown in the photos below - sizes 17 and 18 mm
material: steel colour (nickel plated brass?), brass or gold

Important: bars must have 1 mm diameter tips

I could not find matching new bars - hence my WTB ad


these are the exact dimensions I need:

 

If this kit doesn't have a size that fits, I'd give them a call and see what they can come up with - Single Shoulder Spring Bar Assortment Watch Band Pins (esslinger.com)

I bought two (2) female spring bars from them last month and they accidentally sent me two 10-packs of a completely different item (someone flipped digits on the part number). They corrected their mistake immediately without hassle.

Here you go, called single shoulder.

 

useless because the parts providers don´t offer the dimensions I need - hence my WTB
