Measurement help K98 Bayonet handle! Help

[lugerholsterrepair]

I have here in the shop a K98 bayonet frog that needs a new strap. I need at least a couple of measurements to accurately make one. Ideally, the strap laid flat and an end to end measurement.

Then if you have a bayonet..a front to back and side to side measurement where the bayonet strap wraps around it? I will make a wooden bayonet handle for fitting from this.

Thanks for any help!
