A set of 4 small diamond pattern brass thumbscrews. These are the modern type thread and can be used with most modern plugs with M4 threads (not included).  Have a look at my similar vintage items I have for sale. Please note... I can only post on Tues, Wed, Thurs and sometimes on Friday as I'm away most weekends, I can sometimes answer questions in this period but it may take a while to get back to you. I'm back on Tues. Items will be sent sometimes in recycled packaging and posted by the cheapest method to keep costs down. You may request a postage upgrade at cost extra to me. Items of more than £32 it is recommended (but not compulsory) that you insure for loss or damage. Payments from overseas are pay pal only unless arranged with the seller to pay by another method and must not be updated by the buyer please wait for invoice.  I make sure that the item is packed with care especially fragile items. I will sometimes be able to combine postage on multiple purchases ask before you bid.
