Have rifle s/n 28253 appears little used. Built without bolsters is this a negative. Gun may have been delivered 20 years ? After s/n sequence. Could this have been as a result of popularity of bolsters. Case and gun have largely been in proper storage. One trip to Africa by purchaser in 30s. Gun purchased by Fred. W. Owen of Melbourne Australia. Any thoughts on bolsters. Will try to get mick from Darwin to post photos.
