Tried and True also has a pure version of BLO: Here are two notes we exchanged earlier this week on the topic. I have used their Original Wood Finish before. Might make a good patch lube being beeswax and oil.
Me:
>I am a woodworker and reenactor. I recall you folks, at least for a while, were selling boiled linseed oil made without dryers, which would be similar or perhaps identical to the way it was made a couple hundred years ago. I came to the website to price this, but did not see it offered. Is this product still available for small orders?

>Our Danish Oil would be what you are looking for, it is a 100% pure polymerized linseed oil (PLO). We decided not to call it boiled for a couple of reasons.
>The first being that we do not boil so much as cook in a vacuum, this more modern process is able to produce a more consistant end-product than the traditional kettle "boil" and also eliminates the hazards of heating an oil up to the flash point. The second reason is that nearly every BLO on the market is actually raw oil with metallic drying aids and other chemistries that we do not wish to associate with our products.
>You can use the Danish Oil in any application that would traditionally use linseed oil. I actually season my cast-iron pans with it and I know other people have used it on wrought iron pieces.
>Our two other main finishes - The Original Wood Finish or our Varnish Oil - are also PLO-based and only made with ingredients that would have been available in a pre-industrial world but made with modern quality control and production methods. The Original is PLO and beeswax (works well on leather too) while the Varnish is PLO and pine resin.
>We do not sell anything direct to end consumers anymore, but retail purchases can be made at Woodcraft, Lee Valley, Rockler, Amazon as well as various wood-working/home-improvement stores around North America.
>Please do not hesitate to ask me any further questions!
