Looking at adding a Clarktor 6 to my collection

[Soupermike]

Does anyone have experience with the Clarktor 6 tugs? I have always wanted one since my father worked for Delta Airlines and he would take my brother and I for rides on the tugs they had (obviously pre 9/11). He said that most of the ones Delta had in BTR and MSY were made in the 40's and 50's. There is one for sale close to me and I am not sure what they are worth or if spare parts are available for them.
Any help would be appreciated.
Thanks
Mike

Some pictures would help with an idea of value. I have seen many projects here and there for under $1000. I have a 1944 military tug and a 1963 civilian model, both projects that were $500 each (cheap in my opinion). Some parts seem to be hard to find so I would pay more for a complete one in mostly original condition with things like headlights and brackets, side covers for the engine, air cleaner.
