Hello Jeff,
Here are your diagrams which I have duly "safekept":
I believe the total width of 1 3/32 should be checked against the actual width of the slot on the stock just in case, to allow for good grip for extraction.
Le Lapin has them already.
I translated the disassembly instructions from the 1910 Manufrance catalogue;
This is the original to match the pictures:
Manufrance Idéal Shotgun
Disassembly and Care
The Idéal’s action is of such simplicity that she does not require, so to speak, neither cleaning nor internal lubrication. We recommend expressly not to put oil into the action, through the holes of the firing pins, the sides of the triggers or the under lever, etc. as if this is not a good oil, which is the case nine out of ten times, it will seize the action and prevent the parts of the mechanism moving to the point of sometimes not allowing the firing pins to operate.
The careful hunter will, on returning from the hunt, clean and oil the barrels on the outside and internally, doing it sparingly also to all external metallic parts. If this is done the Idéal will last several generations of hunters.
Lots of owners of Idéals being curious of its innards, we shall indicate the proper way to take it apart.
Each Idéal is delivered with its own kit that includes a hollow screwdriver handle A (figure to the left) that holds three tools B. C. D, used for the disassembly.
(Wish I could find an original one!)
1.- Remove the forend and barrels;
2.- (Fig. 1) With screwdriver C loosen the two screws on top of the action with great care, but -once loose- leave them in place;
3.- (Fig. 2) With the other side of screwdriver C, after removing the small retaining screw, loosen and remove the screw that holds the trigger guard to the action;
4.- (Fig. 3) Insert tool D so as to block the underlug in open position, allowing the under lever to remain depressed fully. Hold the trigger guard and remove cerefully as shown in fig. 3;
(To easily remove it, the screws on top of the action must be loose but in place).
5.- (Fig. 4) Remove tool D, remove the screws from the top of the action, and separate the action from the stock proceeding as indicated on the drawing.
For reassembly invert the procedure.
To all hunters that want to take their Idéal apart we strongly recommend not to force any part, as if there is any difficulty in the disassembly process it is because instructions have not been followed properly; in that case re-read them attentively and follow them exactly. Apart from this complete disassembly we can also, without removing the action from the stock, disassemble separately;
1.- The Loading Indicators.- For this use tool B, as shown in fig. 5;
2.- Firing pin springs.- Proceed as for the Indicators but using the other end of tool B, in other words insert the tool into the holes at the end of the action (fig. 6) and unscrew the long screw which is taken out together with the “rondelle”/(washer?) and the spring.- After cleaning the latter with light oil (pétrol is Diesel fuel) if necessary, re assemble in the same way.Here, the original disassembly instructions can be enlarged.
