This is a very early number 410 (THE LSS CO) Starrett double sided 2 foot rule, with inch divisions. Tempered no4. My research dates this rule to be 1880's (I stand to be corrected)
The rule is extremely rare (I have not found another either for sale or sold in the past)
This Ultra rare Starrett 2ft rule is a collectors piece and is a very hard to source tool with historic interest.
I post to all countries, and combine postage if you buy more than one item. On posting day I will send you tracking details.
