I have been offered this County Jail door and am seeking advice on restoring it, sandblasting, paint color etc. No experience in this area so any advice is welcome.
Trying photobucket, hope it works

Hello,
After looking at the photos some things became readily evident. First the lock itself is smaller / lighter construction for high or maximum security usage. Based upon the pictures the lock seems from about the late 1800's or very early 1900's and this would make sense from the standpoint of a partial Yale catalog reprint from the early 1900's
----------------------------------------------------------------------------------------
-- Lever tumbler deadbolt locks No. 4117 and No. 4118
Adapted for use on swinging plate or grated corridor or cell doors. Lock number 4117 operates from one side. Number 4118 by key from both sides. Each lock is made for a specific hand of door. The lock case measures 3 3/4" x 5 3/4" x 1 1/2" thick and is made of Malleable iron, Japanned. The bolt is made of Bronze with three hardened steel pins inserted in the bolt. The bolt projects when unlocked 11/16". Five bronze tumblers.

As for the other ("night latch") lock on the view port, While yale did make such light duty latch locks for prison use, this one seems even lighter still. However the one thing that confounds me is the lack of fasteners for mounting of the port mounted slam-latch. On a side note the very early yale night latches had 2 very small screws on the latch side - remove those screws and the lock body simply releases from the backer plate underneath. However it's impossible to see this angle from your photos. Also the lock face has relative little wear (gouging) around the plug-face.
The pristine (prison-tine) side of the door would most likly have been on the side (most) exposed to inmates due to the fact that the lock-body is ALMOST ALWAYS mounted on the "secure" (more secure) side of the door as to prevent/limit tampering as well the painted side's lock face has little use compared to the "rust" side's lock face. The bars that are mounted on this side are called "Double Ribbed Hardened Bars" originally used by the Pauly Jail Building Co. Of St Louis Mo. While they were the first to have employed them, by the late 1800's they were by far not the only manufacturer - so it is not definitive as to the maker of the door. I am at a loss as to the additional 3 holes in the angle iron, but they do seem too large diameter for normal bars themselves.
If you wish to make / have made key(s), The rim lock looks like a standard Y1 keyway and if not easily dissasembled, could be impressioned quite easily (your Locksmith friend should be able to do this in about 10 minutes). As for the main door lock, it TOO can be impressioned, However blanks must be handmade, and due to the fact that it has been sitting around soooooooooooo long, the original grease is probably around the viscosity of roofing tar - a situation making the impressioning technique virtually impossible. The best bet if you want a working key is to (very carefully) drill out the flush rivets holding the lock to the door. Be careful as the flush rivets are hour-glass shaped so a 1/4" bit followed by a slightly larger diameter bit, followed by a "step bit drill" should make quick work of removal, replacement mounting to the door can be accomplished with large diameter "sex-bolts & sex nuts" (((PLEASE DON'T ASK WHY THEY'RE CALLED THAT!))) As for the lock once it's in hand flathead screws would normally secure the case to the lock body. After cover is removed, scratchmark all tumblers, spacers and any other part that could be re-assembled out of order. Yes you're looking at about a full day's worth of work to professionally make a key, BUT you must keep in mind one thing: These locks were purpously designed to resist against taking them apart and or crafting working keys, much more so than your front door and it's Kwikset knoblock.
Hope this helps,
Best,

PS. The door lock's key would have had a "tre-foil" shaped head (if you're a purist).
