Is this an allowable RMC fitting for exposed work in the field.

I do not believe it is, but I do not have an NEC reference that says I cannot.
It is found in the plumbing section, but it is only listed as a rigid elbow. 344.24 and Table 2, Chapter 9 gives minimum radius bends, but it is only applied to field bends, not factory fittings. The only other reference I have found to this point is 300.34, dealing with conductor radius bends, but even that is over 600 volts. No need, I do not think, as to the purpose, but is it an allowable fitting?

It's not a bend, field, factory or otherwise. It's a fitting. And a plumbing fitting at that. An elbow, or ninety.

I'll say try 110.3(B).
 
Since it looks like a plumbing fitting the answer would be no. Fittings are required to be approved and typically part of the approval process is that the fitting is used as per it's listing.
 
Crouse Hinds makes listed 90's (and 45's) that are just like the one pictured. Use them occasionally in the tight spaces when replacing fuel dispensers. Not fun, but work in a pinch.
 
Just the wide variety of answers I was expecting. :D The part is listed, as best as I have figured up to this point, as a rigid metal conduit elbow. Not electrical, not plumbing, just rigid.

This is the main reason I considered using it. It is a tight space coming into the bottom of a motor. I am going to use a pulling elbow because I know that it will be right. I just don't like pulling elbows much, mostly for trivial reasons. The listing I am looking at is store listings and not necessarily UL, so my better judgement sees it as not allowed. My search began mainly to see what the required radius of a factory elbow was and, surprisingly, I could not find one.
 
Most of the malleable iron 90 female x female elbow fittings I have seen are classified for use in Hazardous Locations (Class I, II, III). They would be listed for such use and could probably be used for your application as well. C-H has them (1" - cat # EL39).

The fitting in the OP is, specifically, manufactured/imported by LDR Idustries, a plumbing supply manufacturer.

It is one of their line of "SLK - Heavy Duty Fittings" made for plumbing use (the SLK can be seen in the photo in the OP). I could not find specific UL listing identifications in the catalog or on the website.

Here is their online site: http://www.ldrindustries.com/Index.html

Here is the catalog with this fitting:
