this is one have been wondering about for nigh onto a half century...

curious as to the maker behind the symbol on the stem binder bolt head in this image

it is also seen on the heads of seat binders

was current during the 1960's but have no information as to start/stop dates for it

since it appears on both stem binders and seat binders makes me think it a manufacturer of small bits of hardware much as with ALGI of France



thank you for any information
