See cut. Send 5c. for sample shell and bullet. Price for rechambering, $1.00. "
"The cut" does show a bottleneck case.
You can find Harwood's advertisement with "the cut" on page 74 of the No. 5 Ideal Hand Book of Useful Information for Shooters.
Harwood offered reboring of barrels (but not for repeating rifles), bullet casting to order in lots of 250 (grooved or round bullets), Mogg Telescope Sight and scope mounting.
