I recently came into a possession of a seemingly poor quality bow, but after a re-hair and a cleaning I have found it to be of excellent quality. I noticed on the side of the bow it is lightly stamped with "MPS WD 5" (might be MBS or MRS), any idea who or what the maker of this bow could be? It is a wood french bow.. The frog has been swapped out with a glasser bow, but is not the original.
Some pictures might help to identify... If the frog was swapped with a glasser (plastic?) and it is stamped that way, my guess it was in a public school or something.
OK here's something useful. Cheap wooden bows come out of China and elsewhere by the thousand. You will probably never identify it, and to be honest, if it's of such low quality that someone felt ok putting a Glasser frog on the stick, then its almost certainly not worth spending any time trying. If you like it, use it. If not, get rid.
