NRA limited edt.

Question
QUESTION: I have an interarms NRA limited edition .380acp . It is a mid production numbered(only 550 made).
I got it from a "Friends of the NRA Banquet" (1998?) auction. It's in great shape and fired fewer than 6 rounds to test conditions.
The hard case it came in is titled "Mark II" on it.
Located between the trigger and grip is a stamped letter 'm' within a circle.
I have everything except the owners manual (which might be around somewhere)
Two questions, 1- What can I find out about it?(manufactured,value,collector interest?(no, I'm not looking to sell it) 2- Can I find any 'generic' manuals on it ?  
Many thanks for your fine work and dedication to helping all of us.    J.M.M.

ANSWER: Can you attach a photo of it?

NRA ltd 2   QUESTION: As requested here is a photo. I erred in color background. It does not show the true luster of blue/black finish nor the bright gold lettering, hammer and trigger. Also does not show the 'registered like trademark' symbol (M) within a circle on the trigger guard next to grip.   Thanks

Answer
Its a Walther PPK Mark II.
Imported by Interarms, who is long out of business.
Here an owners manual.

In terms of its value I have no listing for this variation.
