chart.....Vessels lost by enemy action 1939 to 1945...?

[rssharpetx]

I have a chart that depicts vessels lost by enemy action from 1939 to 1945 ( between Greenland and New York) It lists 383 wrecks with date and nationality + how it was sunk. There are at least 25 German U boats listed. It looks like blue print type chart and is approx. D size plot. My question is what is the best way to reproduce digitally? The author is Capt. J Prim. 1988. I have tried local print shops etc. They could not handle this size media. This was a gift from Capt. Prim nephew that has since past away.......I will try to contact family for copyright permission so I can distribute free electronically ( once I find best way do reproduce). This is a fascinating chart! Any comments on best approach would be appreciated!

Best Regards

Scott
