Finnish Board Stock

[Dick Herman]

Richard,
I have never examined a Lahti stock or attachment device. However, your question forced me to play with my stuff. The pictured upside down stock attachment is identical to my other artillery rigs and accepted the Artillery Lugers that were inserted. This is a Luger Artillery stock.

There were only some prototype and test shoulder stocks for the Lahti. To find a genuine is really hard.
Most moving around are repros. And even they are rare.

Jussi -

The stock-holster you have shown is very cool; but I was hoping that Dick had a Lahti board stock that he had no use for...So I could buy it from him and use it with an altered Luger artillery holster for my 'artillery Lahti'...

Making a curved attachment iron is outside my skill zone right now; I'm having a hard enough time making a straight one...

Rich, you can do this... think it through.

My suggestion would be either a rotary table cutting the inside curve,... or to do it on the cheap, put the raw attachment iron in a good vise and use a specially ground tool in a fly cutter in your vertical mill that is set up for the appropriate cut radius... Then walk the tool into the iron SLOWLY...

I have thought of that; using a small keyway cutter...But a Luger attching iron would be simpler and quicker...

Here's a pic of the two gripframes...I don't have my verniers handy (I'm taking a motherboard to the PO) but except for the locking notch, the curve looks quite close...

I've seen pics of Lugers with attached board stocks that were at a Gawd-awful angle; I'm guessing that the stock was a Finnish board stock, locked at the Luger notch...Lugers & Lahtis are the only gripframes with external "T" lugs...

I have a Mauser stock iron that I'm using as a design aid, but I really need to find a Luger repro stock iron...

Rich,

Thank you for the pictures. The similarity of the mounting lugs are amazing. The lug lock groove appears to be slightly different. Will a Luger attachment slip onto a Lahti lug?

Dick -

I don't have either attaching iron, but I did just take a couple measurements with my verniers, and I believe a Luger stock iron will fit a Lahti (or can be 'fitted') but a Lahti stock iron won't fit a Luger.

The big difference in dimensions is in the base of the "T" - The Luger is wider. The Luger iron might be a 'sloppier' fit on the Lahti (and the locking notch is in the wrong place) but I think it could be fit. I've been told that Luger attaching iron often needs 'fitting' and repros even more so, but 'fitting' a Luger iron to a Lahti shouldn't be any more work.

That's just my general observation. There's an original Luger arty stock iron on GB right now, but for $195 it can stay there...I can buy an entire repro holster, board stock, straps & pouch for that much...

I'll wait for a repro.

You want a repro Luger stock iron to modify?

...or to just use as a design aid so you can make your own Lahti stock iron?

I won't know which until I get one in hand. A repro is going to need fitting [filing/milling] and will likely be cast iron. If I have to make one it will be steel. I've read here that even original milled steel Luger stock irons may need fitting to another lug, so that's not any real benefit.

I don't like the idea of cast iron; too easy to break off. But if one slipped right on and was reasonable I'd try it. Making my own is possible, but cutting the inside curved slot with a 'T' section is annoying.

Buying the complete repro Luger rig - board stock, holster, straps, pouch etc - is the most reasonable way to get everything together. There's several on eBay/GB for $164 - $175. Not a bad price, but before I invest in something that will only be a desk display I'd want to see if it was easily modified. I don't see any problem with the holster, my concern is the attaching iron. I don't want to re-invent the wheel. If it's too much time & trouble, I'll forget it.
