You're correct! If you look back to the first couple of pics, you can see the beginnings of the the lumps in the form of a 'T'....yet to be fully machined. You can see as yet I have not fully stripped the action as is seen in Brown's book. I suppose that, without the internal parts, might make working on a 'true' monoblock easier but I can't get my mind around that with no real milling machine (Wonder if H & H had one back in the 1800's?) One would need about a 2 1/2" square block to do it. It does make one appreciate the building of a gun. On the other hand, the 'Smith' probably had a roughed out block handed to him by the 12 year old apprentice who labored for days cutting and filing! I think the most difficult gun I built was a wheellock pistol. I can't count the number of times I took it apart trying to figure why it didn't work. One day, I put a bit of powder in the pan and it actually fired......scared me so bad I almost dropped it. Re-discovering 500 year old technology! Bill
