If it’s meant to be springy, it will lose that from being silver soldered. You’d ruin the heat treat it had if it were steel, and it it is brass, you’d have to find a way to cold work it to the point where it was springy again, which would distort it to the point where it wouldn’t fit anymore.
Quench it after soldering.

It is steel, and it is different from the clip on the 101; it has a lip at the bottom which prevents the tone-arm from swinging down too far, unlike the 101, on which the arm swings right down and up a bit to fit the clip on the front of the horn aperture.
It's weak point These clips often break), and I doubt if solder alone would be any use - soft solder would work if you used it to cover the break with a piece of steel (or brass) at the back, but that might make it too rigid. Would quenching it after silver soldering make it too brittle?

Depends I guess. How much does it really need to flex to do its job? Probably very little? What has the OP got to lose?

i should think 1/16 of an inch at the most. You could set it so that the nib on the tone-arm crook didn't engage the bulge in the stop at all, but merely carried on to the positive stop at the bottom. It would be a mild irritation in use, and you'd have to extra careful not to let the soundbox fall back on the record.

Unfortunately I have not been able to find any reference about such a pedestal on the net nor in some HMV catalogues.
Does anyone ever saw one of these or even owns one?
P.S. Attached a picture of the HMV Mod.461 leaflet in an HMV catalogue.
The pedestal has the same footprint as the 460 or 461, with Queen Anne style legs. Also in quarter sawn wood and also arranged in diamond shape. 2 doors. A photo as soon as I move some other pieces out the way!

Thank you Phono48, JerryVan, anchorman and Oedipus for all the suggestions!
This morning I tried to join the two pieces by soft soldering them together (using a variable soldering iron and tin wire with flux core). Although at first this approach appeared to be effective (also from the cosmetic point of view - attached picture) after few hours the clip broke again due to the excessive weight of both the soundbox and short portion of the tonearm.
As soon as possible I will try silver soldering.

Thank you for the reply. That would be great! I really look forward to this.

Have you used silver solder in the past?
