Straps are test models to try out some new needle sizes and thread. The strap overall was secondary, so not 100% and did minimal stitching compared to the original which I thought was overstitched anyways (do you really need double rows on a small loop?) Both straps are 20 x 20 mm - 75/120 mm - 2 mm thick along the main body which I was told the original is and 4 mm at the case. Brown was a test of my current stitching to see if fine enough, but a shade thicker than needed Next model I tried an expensive French linen thread and while fine. I found it a bit more difficult to work with. Also quite expensive per spool. Far more than I’m willing to pay for it. Strap uses a Japanese leather that is hand dyed and surface finished. A 3 month wait due to the finish needing time between coats to properly dry. Price for the brown is $45.00 Price for the black strap is $85.00 Working on a new model, but waiting for other testing threads to arrive Can't be more reasonable on the prices. If a genuine is $500 or so for leather. My prices are dirt cheap $3.50 s/h or $6.50 if overseas Let me know if interested. Thanks DON - [email protected] PS - not taking any requests for these straps
