Question? Vented Spines and Front Visor Trim Sizes

I was wondering if anyone would know what size visor trims and spines are used on size 57 and size 58 helms. From what I have seen helms around size 56 use a 16cm spine and then about a 29.5cm visor trim and then a size 59.5 helm uses about a 17cm spine and about a 30.5cm visor trim.
So I am just curious if anyone would know what size visor trims and spines are used on a size 58 and then a size 57cm helm?

I am working on building up a repro 60cm shell with original fittings the only problem is that from what I have experienced the larger spines and trims are hard to find as all of the trims and spines that I have come across are the 16cm spines and 29.5cm trims, so I am just curious if I would instead go with a 57 or 58 cm shell maybe they would take the smaller size trims that are usually available.
Thank you.

In my experience a 60 cm is exceptional, I can think of 3 that I have seen in 40 years of collecting. A 57 cm is more common than a 58. Of the 58’s I have seen......perhaps 10. Again, my experience only, others here may have encountered more.

Yea the largest m1915 prussian that I have is size 59.5cm everything else usually seems to be around 56cm.

Do you know what the dimensions are for the spine and visor trim on a size 57?

Sorry H, I do not. You could get an approximate size using a cloth measuring tape. The whole spine and trim thing is such a crap shoot! I have literally had 12 brass spines and none would fit. It is very frustrating. 😕
