Some sort of valve or regulator "Premier" British Made. It is brass and aluminium. It has a switch On & Off See my thumb for size comparison.
I like how peoople help answer your questions here. I just joined this site, sorry to post here, but i have an old tilt scale from Measurement Canada that my work was going to scrap for 5$ metal. I couldn't see it go that way. It still looks to be in pretty good shape. May someone please help me navigate how to get my item posted with pictures so I may ask my own "what is this" type question and continue on my journey seeking a proper home for it. I have pictures as well and would like to post them. Any help would be great! Thanks
Hi Mattiius Click on 'Antique Discussion', then on the right side at the top there is a blue space that says 'post new thread', click on that. You upload photos under 'upload a file' button. Use the full image button so your photo is large rather than thumbnail. hope this works for you!
