Boiled and raw Linseed oil are still extensively available.

There are several different forms of "boiled" linseed. As far as true
oils made by prolonged boiling go, they're effectively unavailable.
The stuff sold today as "boiled" is an unboiled warm mixture with a
pre-made drier compound, almost always cobalt-based. The classic
boiled oils used lead, manganese or a mixture of the two cooked into
the oil with prolonged heated. Owing to the lead content, these are
now unavailable - even though their final lead content was only ever a
fraction of a percent, rather than the 30% seen in paint with lead
pigments.

I make my own lead boiled oils, as do a handful of sources for
reenactment purposes (mostly oilcloth, some for firearms stocking).
Selling it is possible, but has paperwork issues. The stuff is very
different to modern "boiled linseed" oils, particularly for its
fexibility and water resistance.

Yuk!

I don't remember seeing any warnings about poisonous constituents before!
They don't put anything in the 'raw' as well do they?
