A section of the San JosŤ plan.
The resolution of the drawings is much higher on the actual plan which is printed on my HP 500 plotter.
Converting them to images that can be displayed on the web results in wider lines.
The price for the San Jose plans is $25 and parts are $80.00 plus postage.
allow me to quote the cost of postage please contact me at
firstname.lastname@example.org with your address and I will calculate the actual postage.
