That Sir,
            is a most interesting piece. What is the bore like? Rifled? If it is ok would be fun to have a shot or two.
Where did you find it?

Cheers

Gordon

Everyone else must post with a paper scale bar from now on! What a great idea.
 Now you must explain the mechanism around the sear. Safety?
                        
 Why is a horizontal sear desribed in books as primitive when it is applied to later English and Dutch locks, when it so refined in earlier Cross bows, wheel locks, snaphaunces, Baltic locks, Mediterranean locks etc? The sear is very refined, it must be only fashion that builders turned away from such a great idea.

The owner is a friend from Moscow.This well-preserved original Puffer.
It is the perfect excuse I made ​​another replica but now I have a lot of work and I need this project postponed.

Horizontal sear... my issue with a horizontal sear is that it engages the wheel with nothing more than a nub at a 90 degree angle through a hole in the plate. At least that is how it is on my wheelock.  Its gracefull but has a tendency of breaking right off.

I do not understand what you're talking. ake a picture that shows what you're talking, I see and respond

[Chris Treichel]

I will take some pictures when I get home.  My Wheelock's (older reproduction) sear is a weak point I have been thinking of reengineering so it won't break.

[Chris Treichel]

On my wheelock the bar sear has this pitiful nub on it that has a tendency of breaking off as it has to hold back the wheel. I am in the process of returning this fellow to service (its not in the greatest shape right now)
I have pulled the sear and placed a nail pointing at the nub being referred to.

you need to change the relationship between "A" and "B" or replace the spring on a much stronger.You introduce a picture of the inside mechanism.

[Chris Treichel]

Thank you, I will take a picture of the insides tonight...

This is a mathematical model of this system.

I removed the plate so you can see the action on the inside of mine. Apparently not the greatest reproduction

[Chris Treichel]

The more I compare this reproduction to your origional the more I see how badly mine one was made... 

[raszpla]

This mechanism is bad Wheelock!
