J.W. car fan

Fellow car enthusiasts-- I am looking at a 19l9 Locomobile Model 48 Roadster for possible purchase. Have seen the car; the seller ran the engine for me (seems fine); and I may be able to go out on a test drive (my inclination is to have the seller drive, as I'm not used to a non-synchromesh manual trans- mission [has to be 'double-clutched', no?) next Sat., December 13th. Any pointers as to what I should look out for in particular? If any of you-all are familiar with Locomobiles, or could refer this on to someone who is, it would be greatly appreciated. Thanks! All the best to you-all in the AACA in the New Year, and a merry Christmas to you. Best regards, J.W. car fan P.S. I'm a lifetime member (since the early '60's) of the AACA.
