| chuck jeweler's lathe and their lathes turn up occasionally in the Boston area. Neither Cope nor DATM list an Alworth. This |
| particular design for a bevel square and this maker's mark have not been seen before by the curator. |

| | 091608T2 | Compass | DTM |
| Steel, 10 1/2" long including the two adjustable 2" long extensions, signed "SULLIVAN'S PAT" "MAR 9, 1880". |
| The angle of the legs can be changed by two locking mechanisms at the ends. The markings on this tool are particularly crisp |
| and clear; the tool is in fine condition. We haven't seen this model of calipers before; this is an uncommonly encountered |
| tool as evidenced by the fact that it is listed in DATM (Nelson 1999) without location, dates of operation, or the first name of |
| Sullivan. DATM also notes obviously incorrect dates of 1980 as well as 1890 on previously reported specimens. Further |
| information on the identity of Sullivan would be greatly appreciated. |
