Thread Introduction:
===================
Welcome to the serial numbers list for Mosrite Combo Models.
Either check this initial post, or go to the most recent post (or close to it) for the most recent update of the list. I've changed the format compared to other lists, so this initial post will be updated, too. The 1st reply of mine (just after this post) will tally up each update.
If you want to link the thread, link the main thread and not one of my replies; I'm likely to delete some of my replies.
======================
Contributing to this List:
======================
If you happen to own a Mosrite Combo of any type and would like to contribute information, I'll need info (and I'd also like pictures, if possible) of these areas:
1 - Pic of the front of the guitar.
2 - Pic of the back of the guitar (to show how the neck is attached - Mosrite usually had a neck plate for these, but sometimes had 3 or 4 screws with ferrules.)
3 - Pic of the sticker seen through the F-hole (if still present.)
4 - Pic of the serial number, stamped into the end of the fretboard near the Neck Pickup (if still present.)
5 - Pic of the headstock, front and top side.
6 - Pic of the headstock, rear.
7 - (Only applies to 6 String Guitars, unless there's somehow a 12 string with this tailpiece) - A pic of the Moseley Tailpiece, where it says "Moseley." Some of the tailpieces have a Patent Number, and I'd like to tell when that starts.
These last 3 are not absolutely necessary, but would also help:
8 - Pic of the Dates on the Potentiometers (if the pots are original.) They come in either Week-Year Format (so 45-66 would be in November 1966) or it's the reverse.
9 - Pic of the Neck Heel where it meets the body (if there's a date stamped, which probably doesn't exist past October 1966.)
10 - Pic of the Neck Pocket (if there's a date, again, which may not exist past October 1966.)
===================

Hxxxx - Red Burst - with Bound F Hole, and Baseplateless Vibrato. Has a Neck Plate. Also has 3 knobs and 2 pickguards and a tortoiseshell truss rod cover, so it seems like Gene Moles assembled this one?
