Pant Identification Please

[JennieRage]

Could you please help me identify the age of these pants and the type of fabric too please?
The material feels heavy and stiff. It is dark green in colour and textured.
Thank you.

Judging by the pattern, cut of the trousers, and exterior suspender buttons, I would guess late 20's/early 30's. As for the fabric, I don't see how it could be anything other than wool.

Thank you MondoFW.
What are the differences in dating with exterior suspender buttons vs. interior?
They don't feel like wool to me but I am nowhere near an expert.
Could they be a cotton and wool blend?
If I recall correctly they feel like how jeans with lycra in them feel.

In that case, these could well be work trousers (they certainly look like them), hence the cotton feel. As for the suspender buttons, I assumed they were older because by the late 30's and the 40's, most trousers had interior buttons. Just my $0.02
