Three days ago I have lost my HP 41C with the Petroleum Fluids Pac.
Fortunately I have another HP 41C but my Petroleum fluids Pac is gone. I have used it for nearly 23 years and I can not live witout their units conversions.
Where I can finding it?.
I read in the archives that David Erdman was able to found one recently.
Thaks for your help
