Rather safe assumption regarding that encased laboratory scale is by Henry Troemner Co. of Philadelphia, PA. A long association between that company and US Government purchasing agents. Used examples still abound, and sell for respectable amounts.
Is the apparatus on left related to the illustration "Surface Welding Apparatus" above their heads to the right? The photos appear to show ideal, acceptable and reject product.
Which fits what the woman standing is doing, that box is surely a lapping turntable.

I've seen tweezers with bone or ivory tips that were used to handle weights because of the fear of steel tweezers scratching them.
I was amazed by the vernier weight rig on some analytical balances. Basically, it consisted of a light chain - one end attached to the weight pan arm, the other to a small drum that could be rotated by a shaft that projected outside the glass case. Turning the shaft caused more or less chain to hang from the balance; a calibrated dial on the drum showed the amount of weight added to the scale arm.

That looks about right - Mediocrates
When you working in fractions of grains weights do need to be small I suppose. My Lee safety scale does just fine for checking powder weight, though I use a modern pocket digital mini-scale (called drug dealer scales by many here in the UK) to check weigh each loaded case (no projectile) and full round for safety and QC (cases are batched when cleaned), though I'm never close to max loads and we don't have pistols which are far more problematic with both double charging and detonating under charging potential.
