Italian Sporting Goods has a gunsmith. Give them a call first before bringing it in though. They may or many not be able to check the head space.

Or Reliable, they're milsurp friendly. They ran through an Enfield I have that hadn't been used in 20-30 yrs, headspace was verified. Or order a set of Okie guages, cheap and then you always have a set.
. i bought a set of okie guages, shipped fast, was like 30$ and i got peace of mind, I bought a mosin with a bolt that matches the bayo and reciver matches buttplate hahahah with a force matched floorplate.
Look at how deep the bolt slides into the receiver. Even if the headspace is off, it isn't going to blow up in your face. Worst that will happen is a light strike.
Mosins are crusty, cranky, crude.... And probably one of the strongest and safest guns ever made.
Shoot it.

Mosin bolt head is interchangeable part that designed to fit over the rim. This makes it absolutely fool proof. If you can't close the bolt on the cartridge then you have something wrong and you need to adress it, if you can then you are good to go.
The bolt heads are interchangeable (by design). If the receiver and barrel are a matched pair (i.e. original) then there is no reason to expect that head space will be a problem.
All the "bolt side" head space dimensions are in the bolt head (from the machined surface through which the firing pin protrudes to the flat side of the locking lugs). If you can still see the fine machining marks on these two surfaces they are fine (not worn).
The "chamber side" head space dimension is from the chamber face (on the barrel assembly) to the rearward face of the locking lugs on the receiver. This is why a matched pair of barrel and receiver are important. Unmatched and you should verify head space.
It is all but impossible to wear out a receiver or bolt head. These two parts are very robustly constructed and the frictional forces between them are very small. You would shoot out many barrels long before wearing to the "Field" limit.
Head space gauges are solution in search of a problem. They are a commercial opportunity just like special bolts and firing pins to prevent "slam fires" in SKSs.
