And the answer is no they did not if the following is indeed a featherweight:

It seems to me properly actioning through lumps offers a greater challenge than those without. And to my way of thinking a perfectly fitted through lump would reduce the strain on the hook. It certainly makes the cleaning of the action much easier.

any work in a blind hole is more difficult to do than in a through hole......

In answer to Mike's answers -

- Yes, we did closely measure many of the Dalys including things like the action thickness (distance between the action flats and bottom of the action.)

- The measurements were not universally thicker of thinner on the through lumped guns - i.e., some of the guns with through lumps had thicker actions and some of the guns with through lumps had thinner actions than the guns without through lumps.

- Yes, there are are featherweight Dalys (and by featherweight Dalys I mean guns actually marked "featherweight" on the rib, not just lightweight Dalys) that do not have a through lump. (I own one myself :-))

As a side note, what became obvious in measuring all these guns was how much hand-work went into filing the action as there was very little commonality in the dimensions. They varied quite a bit from gun to gun. What we half expected to find were a couple standard frame sizes and we didn't really see that.

Steve, are you saying that working in a "blind hole" is more difficult than actioning this Scott's forward lump? Now instead of just fitting it to the pin the lump has to be perfectly fitted to the bottom of the action. If through lugs were easier to make why are modern made guns usually without them?

I"M not trying to start a battle, but through lugs are likely harder to fit,you can see them.The ones I watched being fitted,BTW, didn't have the hinge pin installed until the last step.This makes the process much easier.

Yes, and guns with through lumps can have a larger cross pin, everything else being the same.
Top H&H large caliber double rifle often have a through lump.
I also like through lumps in the sense that one can easily see if the gun has been rejointed (too) many times. The same is true of the doll's head (not so much for Greener cross bolt).

Joe, a blind hole is always harder to do. Also the reason why modern guns don't use through lumps is because of advancements in machines. The sinker edm made it viable.

Sure, one get get sloppy fitting a non through lump since it wasn't visible. But when done properly it will bear on the same surfaces as a through lump and provide the same strength mentioned above by others.

Another reason for through lumps is in the ability to lighten and reduce the size of the action bar and forend. Like mentiened this isn't always the case, just a broad generalization.

I'll continue to stick by that thought.

There are not always "blind"holes in the actions ( I don't have as much experience as you guys but don't remember one that did have one). Most simply have a slot milled from front to rear, the bottom of which is covered by the bottom plate.This slot is closed off by the hinge pin, which is separate.The lumps don't hold the barrels "fore and aft", but do "up and down" and some "side to side"."Fore and aft", I believe the barrels are held by the hinge pin and standing breech. If I'm wrong, it certainly is not the first time.
Mike

Mostly true.
The front of the back lump should participate to the fit to assist the cross pin. However, in many cases it does not due to poor or no fitting.
