Vintage BASHLIN 105 Adjustable Climbing Spikes & Gaffs for Lineman & Lumberjacks

Description

Up for Purchase are the following vintage Bashlin Vintage Adjustable Climbing Spikes & Gaffs Pair with 105 Series Pads.
These were my fathers - Local 176 - and the wear is reflective of his work over the years. The leather is heavy and intact, bTheut it is a challenge to decipher the inscriptions. Here's what I was able to make out:
The Climbing Pads are 105. Newer models have a hyphen after the 105, like '105-BC' - but these say simply 105, as far as I can tell, along with the company name and location.
The Legs are inscribed with the following: "Bashlin, Grove City, Patented"
The very bottom of the legs, where the boot rests, are inscribed with 'L' and 'R' accordingly.
Right above the top of the spike is the number '6'
The ends of the belts are almost illegible, but I do see Grove City, PA
The metal belt loop says 'BASHLIN'
If there's more information I'm missing, just point me in the right direction and I'll try to locate it, but that's everything I was able to find so far.
With that said, while everything is intact, the belts are old, and they haven't been used (tightened) in many years. Will the longer belts last? Probably not, unless there's a way to breath new life into them. Otherwise, expect to replace them unless you're using this pair as decoration.
Currently, the total length of the pair (from the very top to the very bottom) is 20", and since it's adjustable, that figure likely grows based on the current screw placement, though I'd rather not adjust it to find out. I'm fairly certain you already know what these do, either way.
Let me know if you have additional questions. Shipping is based on the actual weight of this item. Thanks for looking!
