This is a nice cond. hanging bubble for a Wild T-4, it is a hard to find accessory (if not impossible until now). It measures 12 inches between the posts w it hangs, and the bubble window measures 8 inches long. It is in good condtion as you can see in the photos, and comes with only what you see, the original wood box. Although Wild did not always match serial numbers of the components, it is nice if they match. I have some other hanging bubbles, so if you have a T-4 with serial numbers 80937 (this one in these photos), 86967, 87018, 56105, 64240, 86977, or 87023 contact me and if you are high bidder, I can swap the hanging level for the one that matches your instrument. I also have a few T-4 Tool Kits in various stages of completeness that I will be selling on ebay in the near future. Priority postage is $25.00 if within the USA, more if ins. is desired or if you are outside the USA. PAYPAL IS THE ONLY ACCEPTABLE FORM OF PAYMENT FOR BIDDERS OUTSIDE THE USA. Other postage options can be arranged if desired, no charge for careful packing.
