Someone I know on another site is having some Semi Auto Vickers right side plates cut. BIG note, you will need to do the finishing, basic .1875" thick which will give you enough thickness to cut out full auto denial islands as required by US Law. Of course US sales only and only where legal. The person having it done has built a legal semi auto Vickers in the past. Cost - would be around $50.00 if enough folks are interested. Again US only, sorry about that. Remember this is extra thick, for semi auto builds and will require a lot more work. I do not believe this planned plate will work in any way for full auto.
If interested in more details please pm me.
