I'm going to throw a spanner in the works. This isn't an issued kit, nor are the items in the roll.Infact I'm pretty sure that the roll and items in it didn't start out life together.
In short this is a home made kit.
As already noted the lettering is most likely someone's initials as here hand written not printed.
I'll list a few observations.
The roll has distinct areas of wear which don't appear to relate to the handle lengths of the items in the roll even allowing for items being replaced in different locations.
The flap at the top is designed to cover the equipment stored in the roll so when it's stowed away the kit doesn't fall out. only the first item is long enough to fit under the flap,so it's unlikely that there related as they counter the function of the pouch,as the can slip out the roll .A similar observation can made for the pins in addition pushing pins through canvas is a pig and blunts them,pretty quickly .
As for items designed for surgical use in the 20 century being made with wooden handles unlikely .As for being a dissection kit there's nothing visible in the picture to dissect with.
The four scribes stick out four a couple of reasons ,one of them is either a replacement or an addition to the set.The two older varnished ones in the middle (straight ,and dog leg) clearly have similar wear patterns which suggests that they were used along an edged surface and as the pattern of is greater on the straight it's likely that what ever they were both used on was recessed.with either a raised machined edge or a sharp edge.So it's unlikely to achive such a ware pattern in poking around in flesh.
Another give away for the repurposing of the pouch is the rust staining it the items are as you found them and it was rolled up then there's no correlation between the kit and the staining and it very unlikely that the staining is from items out side the roll touching it as the rust would have to travel through the items in side.other than the third item from the right which feels out of place. ( and the second on the left which I know I know but I just can't place it at the moment I know I've rebuilt somethings similar in the last eighteen months but I just can't place it.still bugging me that's why I didn't reply sooner.)
It all looks like standard 50's and 60's school art supplies .So I think your instincts to want to re use them to sculpt with is pretty spot on.Infact my first thought was sculpting kit ,then l suspect like most I miss read your comment on playing with ww1 kit and second guessed myself and wondered if it was weapon related.But since you appear to collect vintage air weapons then you'd be. More then familiar with such weapon cleaning kits ,as my thought were leaning initially to this(air weapons)
Just because items are stored together doesn't mean their context is related to their function.Which means I don't think your going to get a better idea until you look at your family tree and research trades education and hobbies.(and Sod's law says it will be something picked up at a yard sale because it looked interesting)
Because the short of it is what ever its intended purpose it's a personalised kit not a pre issued or bought kit.
Or even worse just one of those pottering jobs we all do tidying the shed and a bunch of loose bits that might come in handy have been stored in an old spanner roll just in case.
