The ESP Guitar Company

Hello folks -  I was hoping for a little bit of help. About 25 years ago, I picked up a second hand ESP M-1 in a little local music shop. I'm not entirely certain the guys there were too aware of ESP and maybe just considered it to be a generic "Strat Copy".

I've been wondering for a while about its age and, naturally, its value. I know from the off that it's not one of those I see on e-bay worth thousands - it's not a custom, it's got a rosewood neck, not a throughbody, no floating tremolo and admittedly needs a bit of TLC. I've seen one similar posted on a forum where the guy had taken the neck off and there was a date of 1986 written in pencil, but I don't trust my basic skills to even attempt doing that.

It does have a hockey stick head, a Made in Japan stamp, numbered 6246 and the plate on the neck says 01793. I've attached pictures below.

Any information anyone can give would be much appreciated - due to kids, middle age and a slow realisation that I might not now become a major heavy metal star as I'd once hoped, it's not been played for years, but it would seem a shame not to find out about it if I ever got rid.

You can see it's missing the bit of metal behind the neck whose name I've never actually learned. The metalbarstringthingmajig.

It does say 01793, I think. Got scraped on belt buckles as a teen.

Tremolo back plate is missing sadly, due to me removing it sometime in the mid 90s and being too lazy to have put it back on again.

Many thanks in advance
