The Lattice inside the Arch would suggest Mosely, it's definitely not a Reznor.
I wasn't actually familiar with those designs...its kinda amazing how many unique designs for bowstrings occurred. Even Mosley did a few different models aside from the Hares Hill bridge:
It looked to me like the arch was a T section like the Hares Hill one, hence my leaning with that. Irregardless, its tough doing precision identification based off old postcards :P
I take back my previous comment. I didn't realize Hares Hill was a Moseley design. I think it's arch design doesn't match but the lattice does.
To me it's either a Henszey like this one:
Or a Rezner / Ohio Bridge Co. Like this one:
I'm now leaning towards Henszey as I think the arch cross-section is the same. Moseley has a simpler triangular cross-section so, to me a less likely candidate.
This looks like it might be a small Mosley Lattice bowstring/arch. Compare with the last remaining example:
