i figure this freebie is a '77 canadian built sekine. i have the full list of part codes, & pics for t-mar... some of the parts don't make sense on my shimano parts time chart, but some claim 76/77, which makes perfect sense. i'm new to placing pics on the forum so this may get challenging yet. i'll will make several attempts at posting the pics/parts list with date codes if i fail to post correctly... lets see it this is a sekine model SHB as t-mar predicted...more posts & pics to follow this week.
