I cruised through my local flea market yesterday morning and managed to grab a nice cordovan Parker 51 Deskpen and Onyx Base. As near as I can determine, it's a first year model (circa 1941) with an aluminum speedline Vacumatic filler, no date code, blue diamond on barrel (although blue paint is missing), sharp tapered handle, and Parker imprint on the tapered handle. It's in nice condition and cleaned up quite well, although the filler mechanism will need restoration. Needless to say, I'm quite happy with this score and I'm particularly tickled that it only cost me USD $10!
