I just got one on eBay for less than $5… granted it’s not a VINTAGE one but it is the same shape, same size. The ONLY difference is it is missing the Bard Parker logo on the grip section closest to where the blade goes. But when’s the last time u could read that during H2??? LOL. Here’s a link: https://www.ebay.com/itm/Scalpel-Handle-3L-Surgical-ENT-Veterinary-Instruments/121431954273?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649
The #12 blades are literally almost a dime a dozen so get newhere… but be careful they SHARP!!! I actually have two handles and I used to use one cut eyeholes and such in latex… have since switched to using small sewing scissors. Heres a couple pics of the 3L handle I just got. These are yuuuuge!!! See the ruler pic for reference.
