Many thanks for your replies, all good questions!
The photos are a screen shot from the website where the gun is being advertised.

Police assigned magazines with matching sn's? Didn't know that was done in those days, thanks. Seems to me that if the gun itself is all matching, and since the mags came later, perhaps a reasonable price would be around $1100?

Your expert opinions?

I hope I can get better photos once I see the gun and mags. I'll also be able to answer the questions about the sear and mag safeties / police markings.

Thanks for your comments!!
