M&M Furs Pro tanning solution ?

Thought about tryin my hand at a little tanning.
Lookin through the fur shed, I found a couple of bottles of M&M Furs Pro Tanning "stuff".
It appears that M&M Furs is no longer in business, I could find no information on line.
I'd rather use it, than chuck it.
I need instructions for each bottle?

One of the bottles is marked Pro Tanning Formula.
The second bottle is marked Pro Tanners Leather lube.

Thanks
Jim

If no one here knows, you will probably find someone who does at www.taxidermy.net
