What’s this?

[CaptC]

Found at the bottom of an amateur gunsmiths tool box. I thought it might be for testing trigger pulls but it’s graduated from 0 - 20 lbs. 
Note the curved top end with the screwdriver blade. 
Thanks in advance

What is the printing on the left hand side of the body in the centre picture?

It’s the graduated scale for the spring

Cheers. Could it be some form of adjustable tension meter not necessarily shooting orientated.

if you hold the tube and turn the screw driver end does the screw in the scale move if it does it could be some kind of torque for tightening the screws

No, it's solid - the pointed end pulls the spring as in a spring balance

I think you have answered your question.

Going up to 20lbs. It could be a trigger pull gauge for a Baikal   ??    🤔

It's too fiddly to be a weighing device

Something to-do with Vickers WW1 machine guns.

That’s the one! Well done!

Lewis Machine Gun Spring Trigger Gauge / Combination Tool

Well done every one!

Now for the next one - a strange bipod plus a rest (I see no way they mate together) Last owner added a jubilee clip as he used it with his spotting scope. 
Looks like a bipod from a machine gun but the angle of dangle is shallow. The legs measure 13” long. 
Thanks again!

I think there's a bit missing, a bar that fits into the clamped holes in both parts and joins the two.

I'd also say the Jubilee clip/clamp is original, given the use of the previous item I'm going to say it's for a Lewis gun.

I think you are correct. Googling came up with the correct clamp. Thank you
