just noticed that 53 too . odd bridge arrangement . bigsby add on , back color looks too red to me . might be right but I think they are mostly natural back or dark back . looks good but .... sure would like to see it up close . I have 2 refined GTs '52/'53 one with a dogbone/ b-5 bigsby set up and one that has been converted to a stoptail . love these early GTs .
