I realize that these may have Belgian origins.

I'd guess the following Mainwarings to have similar component configurations:




Curious why some are blue and some are not; maybe to differentiate between pen and peg?

In Rainey's pictures you can see that the locks are basically all the same and probably copied after Holland and Holland. You can also see that there are 5 screw posts (blued) and 3 polished screw posts acting as axels, that is counting the one on the long leg of the lock that holds the mainspring in place. Someone years ago came up with the bright idea of using the tumbler axel as a cocking indicator by putting a slot in it.

Before the turn of the last century, many of the lock plates were machined out to hold the mainspring in.

Some of the best locks are engine turned supposedly to hold a light film of oil.

Thanks JDW. I meant to start with the Purdey backaction and move to psuedo H&H bar action. I can extract some of the images of the following Purdey lockwork and post if anyone desires:

I don't concur with the stigma that a sidelock is superior to a A&D action body. Both have their merits.

Guys, this was all very helpful and I appreciate the effort!!!! I think Rocketman had it correct in that it depends on whether you count the striker pivot/axle and mainspring pin as a PIN or NOT. The Englishman counted both as pins and that is why he called it a 9 pin but most people would call it a 7 pin and not count these two attachment points.

I hope this discussion also helps some others on the site that might be equally challenged by the terminology of sidelock actions.

Just curious, my Verney-Carron sidelock ejector (as shown on the VC discussion forum) is a back action. How do I determine which is the mainspring pin?

Paul

Paul's V-C back-action - If I read it correctly, the mainspring should be just above the connecting screw


H&H back action as found on Hallowellco


Purdey back action as found on DGS


Purdey - Beesley as found on Hallowellco


Gastinne Renette back action as found on Hallowellco

Seems it all depends if you fancy a back action sidelock or a bar action sidelock and how you define the pins, pegs & axels

The pin configuration on this W&S looks interesting and I think it to be a back action:

So this is the W&R(Webley & John Rogers) back action platform?

Raimey, as usual, I think you have nailed my question concerning my particular 7 pin back action sidelock. I know that it all depends on what type of action but knowing where the mainspring screw is very helpful on a back action. Bar actions are a bit easier.

Once again, I want to extend my thanks to "all that have contributed" to this thread and have further my on going education regarding sidelocks. There is so much to learn and so little time to learn it all. Guess that is why I like this forum so much---very helpful replies and knowledgeable people always willing to share!!!!

I think a lot of us have learned a great deal, good thread Paul.

It was also interesting to see all of those differing actions. I�ll never get tired of looking at and studying, sidelocks.

There is a fantastic 396-page book named "Platines" by Laurent Bedu, that describes the most common sidelock systems: Beesley, Holland, "Scott", etc... and also includes the Italian ones Betretta, Zanotti, ... and the obscure ones such as Defourny and Francotte FASD.
The book is in French but I know that the author is working on an English translation.
Highly recommended.
