I have both a COB pre-serial number Suprphonic and an early Ludaloy supra (Serial number indicates 1965 vintage). To raise money for another project, one of them may get booted. Pricing seems all over the place. I can't believe that the COB would fetch nearly a grand, but I've seen some offered and sold in this range. Neither drum is perfect. In fact the condition of each is very similar. A few scratches. There's almost no pitting on the non-COB drum. Would appreciate some advice on the value of each - and any thoughts on why I might wish to keep one over the other.
Thanks
