Les. Dunsdon Bow String

[tinkering]

I have a small Len Dunsdon recurve bow from the 50s or 60s. There is no model indication, just a decal on the belly of the upper limb 'Les. Dunsdon, Brantford, Ont.' and a hand written 'R 5.' on the side of the lower limb under the simple red rubber handle. It is solid fiberglass construction. I would like to string it to see what the draw weight is.
Has anyone ever seen one of these?
Is it a kid's bow, or a trainer of some kind?
Measuring from nock groove to nock groove along the belly is 49" which I think is the AMO, which would mean a 45" string. Sound right?
How does the number of strings designation usually work? I doubt this bow would be more than 40 lbs draw weight. Would this mean a bow string with 12 strands?
I will attach a few pictures if possible.

The limbs are just under 3/4" at the widest.

Look up Chad weaver, he’s in the states. Best bowstrings I’ve ever seen and he’ll know how long to make it.

I might jist use the method for determining a bow's AMO and then shorting it 4" like you're supposed to do with recurves. R/Ds and longbow subtract a different value... can't remember the numbers...
I want to string this thing up cheaply until I see what it is. I don't want the string worth more than the bow

AMO 49"
Minus 4" for recurves
I'll try Amazon for a 45" string with 12 strands, and see what happens.
I guess🤠
